Trait IntoResponse 

pub trait IntoResponse {
    // Required method
    fn into_response(self) -> Response;
}

Implemented by any type that can be turned into an HTTP Response.

Implement this on your application error enum so handlers can return Result<Response, MyError> and the framework maps the error to the correct HTTP status automatically.

Response itself implements IntoResponse as the identity conversion.

Required Methods

fn into_response(self) -> Response

Dyn Compatibility

In older versions of Rust, dyn compatibility was called "object safety".
