Commits on Mar 21, 2024

  1. Add new traits and types to improve error handling user experience. 

    Adds the trait `IntoResultResponse` to be use in place of
`IntoResponse` in handlers to allow easy use of `?` on standard errors
and other implementations like `anyhow` and `eyre`.

The type `ErrorResponse` encapsulate any kind of error with an associated
`StatusCode` and the type alias `ResultResponse` use it by default in a
`Result`.

`ErrorResponse` can be converted from any `Into<Box<dyn Error>>` and
also implements `IntoResponse`.

`IntoResultResponse` is only implemented by `ResultResponse` to force the
type system to unambiguously convert any errors from handlers to
`ErrorResponse` when using `?`.

This commits only add new traits and types doesn't change any existing
API.
