## METADATA
| Property | Value | Notes |
| -------- | ----- | ----- |
| generator name | rust-axum | pass this to the generate command after -g |
| generator stability | BETA | |
| generator type | SERVER | |
| generator language | Rust | |
| generator default templating engine | mustache | |
| helpTxt | Generates a Rust server library which bases on Axum. | |
## CONFIG OPTIONS
These options may be applied as additional-properties (cli) or configOptions (plugins). Refer to [configuration docs](https://openapi-generator.tech/docs/configuration) for more details.
| Option | Description | Values | Default |
| ------ | ----------- | ------ | ------- |
|allowBlockingResponseSerialize|By default, json/form-urlencoded response serialization, which might perform a lot of compute in a future without yielding, is executed on a blocking thread via tokio::task::spawn_blocking. Set this option to true will override this behaviour and allow blocking call to happen. It helps to improve the performance when response serialization (e.g. returns tiny data) is low cost.| |false|
|allowBlockingValidator|By default, validation process, which might perform a lot of compute in a future without yielding, is executed on a blocking thread via tokio::task::spawn_blocking. Set this option to true will override this behaviour and allow blocking call to happen. It helps to improve the performance when validating request-data (header, path, query, body) is low cost.| |false|
|disableValidator|Disable validating request-data (header, path, query, body) against OpenAPI Schema Specification.| |false|
|packageName|Rust crate name (convention: snake_case).| |openapi|
|packageVersion|Rust crate version.| |null|

# Rust API for {{{packageName}}}
{{#appDescriptionWithNewLines}}
{{{.}}}
{{/appDescriptionWithNewLines}}
## Overview
This server was generated by the [openapi-generator]
(https://openapi-generator.tech) project. By using the
[OpenAPI-Spec](https://github.com/OAI/OpenAPI-Specification) from a remote
server, you can easily generate a server stub.
To see how to make this your own, look here: [README]((https://openapi-generator.tech))
- API version: {{{appVersion}}}
{{^hideGenerationTimestamp}}- Build date: {{{generatedDate}}}{{/hideGenerationTimestamp}}
{{#infoUrl}}For more information, please visit [{{{infoUrl}}}]({{{infoUrl}}}){{/infoUrl}}
This autogenerated project defines an API crate `{{{packageName}}}` which contains:
* An `Api` trait defining the API in Rust.
* Data types representing the underlying data model.
* Axum router which accepts HTTP requests and invokes the appropriate `Api` method for each operation.
* Request validations (path, query, body params) are included.
## Using the generated library
The generated library has a few optional features that can be activated through Cargo.
* `server`
* This defaults to enabled and creates the basic skeleton of a server implementation based on Axum.
* To create the server stack you'll need to provide an implementation of the API trait to provide the server function.
* `conversions`
* This defaults to disabled and creates extra derives on models to allow "transmogrification" between objects of structurally similar types.
See https://doc.rust-lang.org/cargo/reference/manifest.html#the-features-section for how to use features in your `Cargo.toml`.
### Example
```rust
struct ServerImpl {
// database: sea_orm::DbConn,
}
#[allow(unused_variables)]
#[async_trait]
impl {{{packageName}}}::Api for ServerImpl {
// API implementation goes here
}
pub async fn start_server(addr: &str) {
// initialize tracing
tracing_subscriber::fmt::init();
// Init Axum router
let app = {{{packageName}}}::server::new(Arc::new(ServerImpl));
// Add layers to the router
let app = app.layer(...);
// Run the server with graceful shutdown
let listener = TcpListener::bind(addr).await.unwrap();
axum::serve(listener, app)
.with_graceful_shutdown(shutdown_signal())
.await
.unwrap();
}
async fn shutdown_signal() {
let ctrl_c = async {
signal::ctrl_c()
.await
.expect("failed to install Ctrl+C handler");
};
#[cfg(unix)]
let terminate = async {
signal::unix::signal(signal::unix::SignalKind::terminate())
.expect("failed to install signal handler")
.recv()
.await;
};
#[cfg(not(unix))]
let terminate = std::future::pending::<()>();
tokio::select! {
_ = ctrl_c => {},
_ = terminate => {},
}
}
```

# OpenAPI Generator Ignore
# Generated by openapi-generator https://github.com/openapitools/openapi-generator
# Use this file to prevent files from being overwritten by the generator.
# The patterns follow closely to .gitignore or .dockerignore.
# As an example, the C# client generator defines ApiClient.cs.
# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
#ApiClient.cs
# You can match any string of characters against a directory, file or extension with a single asterisk (*):
#foo/*/qux
# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
#foo/**/qux
# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
# You can also negate patterns with an exclamation (!).
# For example, you can ignore all files in a docs folder with the file extension .md:
#docs/*.md
# Then explicitly reverse the ignore rule for a single file:
#!docs/README.md

# Rust API for multipart-v3
API under test
## Overview
This server was generated by the [openapi-generator]
(https://openapi-generator.tech) project. By using the
[OpenAPI-Spec](https://github.com/OAI/OpenAPI-Specification) from a remote
server, you can easily generate a server stub.
To see how to make this your own, look here: [README]((https://openapi-generator.tech))
- API version: 1.0.7
This autogenerated project defines an API crate `multipart-v3` which contains:
* An `Api` trait defining the API in Rust.
* Data types representing the underlying data model.
* Axum router which accepts HTTP requests and invokes the appropriate `Api` method for each operation.
* Request validations (path, query, body params) are included.
## Using the generated library
The generated library has a few optional features that can be activated through Cargo.
* `server`
* This defaults to enabled and creates the basic skeleton of a server implementation based on Axum.
* To create the server stack you'll need to provide an implementation of the API trait to provide the server function.
* `conversions`
* This defaults to disabled and creates extra derives on models to allow "transmogrification" between objects of structurally similar types.
See https://doc.rust-lang.org/cargo/reference/manifest.html#the-features-section for how to use features in your `Cargo.toml`.
### Example
```rust
struct ServerImpl {

# OpenAPI Generator Ignore
# Generated by openapi-generator https://github.com/openapitools/openapi-generator
# Use this file to prevent files from being overwritten by the generator.
# The patterns follow closely to .gitignore or .dockerignore.
# As an example, the C# client generator defines ApiClient.cs.
# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
#ApiClient.cs
# You can match any string of characters against a directory, file or extension with a single asterisk (*):
#foo/*/qux
# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
#foo/**/qux
# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
# You can also negate patterns with an exclamation (!).
# For example, you can ignore all files in a docs folder with the file extension .md:
#docs/*.md
# Then explicitly reverse the ignore rule for a single file:
#!docs/README.md

# Rust API for openapi-v3
API under test
## Overview
This server was generated by the [openapi-generator]
(https://openapi-generator.tech) project. By using the
[OpenAPI-Spec](https://github.com/OAI/OpenAPI-Specification) from a remote
server, you can easily generate a server stub.
To see how to make this your own, look here: [README]((https://openapi-generator.tech))
- API version: 1.0.7
This autogenerated project defines an API crate `openapi-v3` which contains:
* An `Api` trait defining the API in Rust.
* Data types representing the underlying data model.
* Axum router which accepts HTTP requests and invokes the appropriate `Api` method for each operation.
* Request validations (path, query, body params) are included.
## Using the generated library
The generated library has a few optional features that can be activated through Cargo.
* `server`
* This defaults to enabled and creates the basic skeleton of a server implementation based on Axum.
* To create the server stack you'll need to provide an implementation of the API trait to provide the server function.
* `conversions`
* This defaults to disabled and creates extra derives on models to allow "transmogrification" between objects of structurally similar types.
See https://doc.rust-lang.org/cargo/reference/manifest.html#the-features-section for how to use features in your `Cargo.toml`.
### Example
```rust
struct ServerImpl {
// database: sea_orm::DbConn,
}
#[allow(unused_variables)]
#[async_trait]
impl openapi-v3::Api for ServerImpl {
// API implementation goes here
}
pub async fn start_server(addr: &str) {
// initialize tracing
tracing_subscriber::fmt::init();
// Init Axum router
let app = openapi-v3::server::new(Arc::new(ServerImpl));
// Add layers to the router
let app = app.layer(...);
// Run the server with graceful shutdown
let listener = TcpListener::bind(addr).await.unwrap();
axum::serve(listener, app)
.with_graceful_shutdown(shutdown_signal())
.await
.unwrap();
}
async fn shutdown_signal() {
let ctrl_c = async {
signal::ctrl_c()
.await
.expect("failed to install Ctrl+C handler");
};
#[cfg(unix)]
let terminate = async {
signal::unix::signal(signal::unix::SignalKind::terminate())
.expect("failed to install signal handler")
.recv()
.await;
};
#[cfg(not(unix))]
let terminate = std::future::pending::<()>();
tokio::select! {
_ = ctrl_c => {},
_ = terminate => {},
}
}
```

# OpenAPI Generator Ignore
# Generated by openapi-generator https://github.com/openapitools/openapi-generator
# Use this file to prevent files from being overwritten by the generator.
# The patterns follow closely to .gitignore or .dockerignore.
# As an example, the C# client generator defines ApiClient.cs.
# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
#ApiClient.cs
# You can match any string of characters against a directory, file or extension with a single asterisk (*):
#foo/*/qux
# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
#foo/**/qux
# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
# You can also negate patterns with an exclamation (!).
# For example, you can ignore all files in a docs folder with the file extension .md:
#docs/*.md
# Then explicitly reverse the ignore rule for a single file:
#!docs/README.md

# Rust API for ops-v3
No description provided (generated by Openapi Generator https://github.com/openapitools/openapi-generator)
## Overview
This server was generated by the [openapi-generator]
(https://openapi-generator.tech) project. By using the
[OpenAPI-Spec](https://github.com/OAI/OpenAPI-Specification) from a remote
server, you can easily generate a server stub.
To see how to make this your own, look here: [README]((https://openapi-generator.tech))
- API version: 0.0.1
This autogenerated project defines an API crate `ops-v3` which contains:
* An `Api` trait defining the API in Rust.
* Data types representing the underlying data model.
* Axum router which accepts HTTP requests and invokes the appropriate `Api` method for each operation.
* Request validations (path, query, body params) are included.
## Using the generated library
The generated library has a few optional features that can be activated through Cargo.
* `server`
* This defaults to enabled and creates the basic skeleton of a server implementation based on Axum.
* To create the server stack you'll need to provide an implementation of the API trait to provide the server function.
* `conversions`
* This defaults to disabled and creates extra derives on models to allow "transmogrification" between objects of structurally similar types.
See https://doc.rust-lang.org/cargo/reference/manifest.html#the-features-section for how to use features in your `Cargo.toml`.
### Example
```rust
struct ServerImpl {
// database: sea_orm::DbConn,
}
#[allow(unused_variables)]
#[async_trait]
impl ops-v3::Api for ServerImpl {
// API implementation goes here
}
pub async fn start_server(addr: &str) {
// initialize tracing
tracing_subscriber::fmt::init();
// Init Axum router
let app = ops-v3::server::new(Arc::new(ServerImpl));
// Add layers to the router
let app = app.layer(...);
// Run the server with graceful shutdown
let listener = TcpListener::bind(addr).await.unwrap();
axum::serve(listener, app)
.with_graceful_shutdown(shutdown_signal())
.await
.unwrap();
}
async fn shutdown_signal() {
let ctrl_c = async {
signal::ctrl_c()
.await
.expect("failed to install Ctrl+C handler");
};
#[cfg(unix)]
let terminate = async {
signal::unix::signal(signal::unix::SignalKind::terminate())
.expect("failed to install signal handler")
.recv()
.await;
};
#[cfg(not(unix))]
let terminate = std::future::pending::<()>();
tokio::select! {
_ = ctrl_c => {},
_ = terminate => {},
}
}
```

# OpenAPI Generator Ignore
# Generated by openapi-generator https://github.com/openapitools/openapi-generator
# Use this file to prevent files from being overwritten by the generator.
# The patterns follow closely to .gitignore or .dockerignore.
# As an example, the C# client generator defines ApiClient.cs.
# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
#ApiClient.cs
# You can match any string of characters against a directory, file or extension with a single asterisk (*):
#foo/*/qux
# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
#foo/**/qux
# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
# You can also negate patterns with an exclamation (!).
# For example, you can ignore all files in a docs folder with the file extension .md:
#docs/*.md
# Then explicitly reverse the ignore rule for a single file:
#!docs/README.md

# Rust API for petstore-with-fake-endpoints-models-for-testing
This spec is mainly for testing Petstore server and contains fake endpoints, models. Please do not use this for any other purpose. Special characters: \" \\
## Overview
This server was generated by the [openapi-generator]
(https://openapi-generator.tech) project. By using the
[OpenAPI-Spec](https://github.com/OAI/OpenAPI-Specification) from a remote
server, you can easily generate a server stub.
To see how to make this your own, look here: [README]((https://openapi-generator.tech))
- API version: 1.0.0
This autogenerated project defines an API crate `petstore-with-fake-endpoints-models-for-testing` which contains:
* An `Api` trait defining the API in Rust.
* Data types representing the underlying data model.
* Axum router which accepts HTTP requests and invokes the appropriate `Api` method for each operation.
* Request validations (path, query, body params) are included.
## Using the generated library
The generated library has a few optional features that can be activated through Cargo.
* `server`
* This defaults to enabled and creates the basic skeleton of a server implementation based on Axum.
* To create the server stack you'll need to provide an implementation of the API trait to provide the server function.
* `conversions`
* This defaults to disabled and creates extra derives on models to allow "transmogrification" between objects of structurally similar types.
See https://doc.rust-lang.org/cargo/reference/manifest.html#the-features-section for how to use features in your `Cargo.toml`.
### Example
```rust
struct ServerImpl {
// database: sea_orm::DbConn,
}
#[allow(unused_variables)]
#[async_trait]
impl petstore-with-fake-endpoints-models-for-testing::Api for ServerImpl {
// API implementation goes here
}
pub async fn start_server(addr: &str) {
// initialize tracing
tracing_subscriber::fmt::init();
// Init Axum router
let app = petstore-with-fake-endpoints-models-for-testing::server::new(Arc::new(ServerImpl));
// Add layers to the router
let app = app.layer(...);
// Run the server with graceful shutdown
let listener = TcpListener::bind(addr).await.unwrap();
axum::serve(listener, app)
.with_graceful_shutdown(shutdown_signal())
.await
.unwrap();
}
async fn shutdown_signal() {
let ctrl_c = async {
signal::ctrl_c()
.await
.expect("failed to install Ctrl+C handler");
};
#[cfg(unix)]
let terminate = async {
signal::unix::signal(signal::unix::SignalKind::terminate())
.expect("failed to install signal handler")
.recv()
.await;
};
#[cfg(not(unix))]
let terminate = std::future::pending::<()>();
tokio::select! {
_ = ctrl_c => {},
_ = terminate => {},
}
}
```

# OpenAPI Generator Ignore
# Generated by openapi-generator https://github.com/openapitools/openapi-generator
# Use this file to prevent files from being overwritten by the generator.
# The patterns follow closely to .gitignore or .dockerignore.
# As an example, the C# client generator defines ApiClient.cs.
# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
#ApiClient.cs
# You can match any string of characters against a directory, file or extension with a single asterisk (*):
#foo/*/qux
# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
#foo/**/qux
# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
# You can also negate patterns with an exclamation (!).
# For example, you can ignore all files in a docs folder with the file extension .md:
#docs/*.md
# Then explicitly reverse the ignore rule for a single file:
#!docs/README.md

# Rust API for petstore
This is a sample server Petstore server. For this sample, you can use the api key `special-key` to test the authorization filters.
## Overview
This server was generated by the [openapi-generator]
(https://openapi-generator.tech) project. By using the
[OpenAPI-Spec](https://github.com/OAI/OpenAPI-Specification) from a remote
server, you can easily generate a server stub.
To see how to make this your own, look here: [README]((https://openapi-generator.tech))
- API version: 1.0.0
This autogenerated project defines an API crate `petstore` which contains:
* An `Api` trait defining the API in Rust.
* Data types representing the underlying data model.
* Axum router which accepts HTTP requests and invokes the appropriate `Api` method for each operation.
* Request validations (path, query, body params) are included.
## Using the generated library
The generated library has a few optional features that can be activated through Cargo.
* `server`
* This defaults to enabled and creates the basic skeleton of a server implementation based on Axum.
* To create the server stack you'll need to provide an implementation of the API trait to provide the server function.
* `conversions`
* This defaults to disabled and creates extra derives on models to allow "transmogrification" between objects of structurally similar types.
See https://doc.rust-lang.org/cargo/reference/manifest.html#the-features-section for how to use features in your `Cargo.toml`.
### Example
```rust
struct ServerImpl {
// database: sea_orm::DbConn,
}
#[allow(unused_variables)]
#[async_trait]
impl petstore::Api for ServerImpl {
// API implementation goes here
}
pub async fn start_server(addr: &str) {
// initialize tracing
tracing_subscriber::fmt::init();
// Init Axum router
let app = petstore::server::new(Arc::new(ServerImpl));
// Add layers to the router
let app = app.layer(...);
// Run the server with graceful shutdown
let listener = TcpListener::bind(addr).await.unwrap();
axum::serve(listener, app)
.with_graceful_shutdown(shutdown_signal())
.await
.unwrap();
}
async fn shutdown_signal() {
let ctrl_c = async {
signal::ctrl_c()
.await
.expect("failed to install Ctrl+C handler");
};
#[cfg(unix)]
let terminate = async {
signal::unix::signal(signal::unix::SignalKind::terminate())
.expect("failed to install signal handler")
.recv()
.await;
};
#[cfg(not(unix))]
let terminate = std::future::pending::<()>();
tokio::select! {
_ = ctrl_c => {},
_ = terminate => {},
}
}
```

# OpenAPI Generator Ignore
# Generated by openapi-generator https://github.com/openapitools/openapi-generator
# Use this file to prevent files from being overwritten by the generator.
# The patterns follow closely to .gitignore or .dockerignore.
# As an example, the C# client generator defines ApiClient.cs.
# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
#ApiClient.cs
# You can match any string of characters against a directory, file or extension with a single asterisk (*):
#foo/*/qux
# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
#foo/**/qux
# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
# You can also negate patterns with an exclamation (!).
# For example, you can ignore all files in a docs folder with the file extension .md:
#docs/*.md
# Then explicitly reverse the ignore rule for a single file:
#!docs/README.md

[OpenAPI-Spec](https://github.com/OAI/OpenAPI-Specification) from a remote
server, you can easily generate a server stub.
To see how to make this your own, look here: [README]((https://openapi-generator.tech))
- API version: 1.0
This autogenerated project defines an API crate `ping-bearer-auth` which contains:
* An `Api` trait defining the API in Rust.
* Data types representing the underlying data model.
* Axum router which accepts HTTP requests and invokes the appropriate `Api` method for each operation.
* Request validations (path, query, body params) are included.
## Using the generated library
The generated library has a few optional features that can be activated through Cargo.
* `server`
* This defaults to enabled and creates the basic skeleton of a server implementation based on Axum.
* To create the server stack you'll need to provide an implementation of the API trait to provide the server function.
* `conversions`
* This defaults to disabled and creates extra derives on models to allow "transmogrification" between objects of structurally similar types.
See https://doc.rust-lang.org/cargo/reference/manifest.html#the-features-section for how to use features in your `Cargo.toml`.
### Example
```rust
struct ServerImpl {
// database: sea_orm::DbConn,
}
#[allow(unused_variables)]
#[async_trait]
impl ping-bearer-auth::Api for ServerImpl {
// API implementation goes here
}
pub async fn start_server(addr: &str) {
// initialize tracing
tracing_subscriber::fmt::init();
// Init Axum router
let app = ping-bearer-auth::server::new(Arc::new(ServerImpl));
// Add layers to the router
let app = app.layer(...);
// Run the server with graceful shutdown
let listener = TcpListener::bind(addr).await.unwrap();
axum::serve(listener, app)
.with_graceful_shutdown(shutdown_signal())
.await
.unwrap();
}
async fn shutdown_signal() {
let ctrl_c = async {
signal::ctrl_c()
.await
.expect("failed to install Ctrl+C handler");
};
#[cfg(unix)]
let terminate = async {
signal::unix::signal(signal::unix::SignalKind::terminate())
.expect("failed to install signal handler")
.recv()
.await;
};
#[cfg(not(unix))]
let terminate = std::future::pending::<()>();
tokio::select! {
_ = ctrl_c => {},
_ = terminate => {},
}
}
```

# OpenAPI Generator Ignore
# Generated by openapi-generator https://github.com/openapitools/openapi-generator
# Use this file to prevent files from being overwritten by the generator.
# The patterns follow closely to .gitignore or .dockerignore.
# As an example, the C# client generator defines ApiClient.cs.
# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
#ApiClient.cs
# You can match any string of characters against a directory, file or extension with a single asterisk (*):
#foo/*/qux
# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
#foo/**/qux
# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
# You can also negate patterns with an exclamation (!).
# For example, you can ignore all files in a docs folder with the file extension .md:
#docs/*.md
# Then explicitly reverse the ignore rule for a single file:
#!docs/README.md
