### ⚠ `roadster` breaking changes

```text
--- failure derive_trait_impl_removed: built-in derived trait no longer implemented ---

Description:
A public type has stopped deriving one or more traits. This can break downstream code that depends on those types implementing those traits.
        ref: https://doc.rust-lang.org/reference/attributes/derive.html#derive
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.40.0/src/lints/derive_trait_impl_removed.ron

Failed in:
  type CustomOnRequest no longer derives Copy, in /tmp/.tmpdSSYMj/roadster/src/service/http/middleware/tracing/mod.rs:154

--- failure method_parameter_count_changed: pub method parameter count changed ---

Description:
A publicly-visible method now takes a different number of parameters.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#fn-change-arity
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.40.0/src/lints/method_parameter_count_changed.ron

Failed in:
  roadster::service::http::middleware::tracing::CustomOnResponse::new now takes 1 parameters instead of 0, in /tmp/.tmpdSSYMj/roadster/src/service/http/middleware/tracing/mod.rs:210

--- failure struct_marked_non_exhaustive: struct marked #[non_exhaustive] ---

Description:
A public struct has been marked #[non_exhaustive], which will prevent it from being constructed using a struct literal outside of its crate. It previously had no private fields, so a struct literal could be used to construct it outside its crate.
        ref: https://doc.rust-lang.org/cargo/reference/semver.html#attr-adding-non-exhaustive
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.40.0/src/lints/struct_marked_non_exhaustive.ron

Failed in:
  struct CustomOnRequest in /tmp/.tmpdSSYMj/roadster/src/service/http/middleware/tracing/mod.rs:154

--- failure unit_struct_changed_kind: unit struct changed kind ---

Description:
A public unit struct has been changed to a normal (curly-braces) struct, which cannot be constructed using the same struct literal syntax.
        ref: rust-lang/cargo#10871
       impl: https://github.com/obi1kenobi/cargo-semver-checks/tree/v0.40.0/src/lints/unit_struct_changed_kind.ron

Failed in:
  struct CustomOnRequest in /tmp/.tmpdSSYMj/roadster/src/service/http/middleware/tracing/mod.rs:154
```
