* Fix compilation error when validate is used on Nullable values
* Update samples
* Switch Nullable Into Option trait implement to From
* Update samples from rebase
* fix: Respect `disableValidator` CLI option
Setting the `disableValidator` option to `true` used to generate
validation code but avoid calling it from the route handlers.
This generated invalid code in some cases.
This commit renders the `server-operation-validate` only, when the
`disableValidator` option is set to false (the default value).
* test: Update examples and run integration test
The generated samples are updated with:
`./bin/generate-samples.sh ./bin/configs/manual/*.yaml`
The relevant integration test
`mvn integration-test -f samples/server/petstore/rust-axum/pom.xml`
passes.
* test: Add integration test
This integration tests provokes the generation of code that would
not compile (see #18580). The new change that makes sure validation
logic is not rendered when disabled, makes sure the faulty code is not
generated and therefore the project compiles.
* test: Update examples and run integration test
The generated samples are updated with:
`./bin/generate-samples.sh ./bin/configs/manual/*.yaml`
The relevant integration test
`mvn integration-test -f samples/server/petstore/rust-axum/pom.xml`
passes.
