Subject: [PATCH] fix(rust, client): fix breaking regression introduced by
 #10432 (#10720)

* Fix breaking regression introduced by #10432

This change forgot enum structures, which causes the compiler to throw errors for "the trait `Default` is not implemented for MyEnum".
This change implements the Default trait to the enum template.

* fix: add Default for type enums
