Trait for errors that can be converted to HTTP responses

Implement this trait on your domain errors to customize the HTTP status code and message that will be returned when the error is converted to a response.

§Example

use ferro_rs::HttpError;

#[derive(Debug)]
struct UserNotFoundError { user_id: i32 }

impl std::fmt::Display for UserNotFoundError {
    fn fmt(&self, f: &mut std::fmt::Formatter<'_>) -> std::fmt::Result {
        write!(f, "User {} not found", self.user_id)
    }
}

impl std::error::Error for UserNotFoundError {}

impl HttpError for UserNotFoundError {
    fn status_code(&self) -> u16 { 404 }
}
