Enum ResponseError

pub enum ResponseError {
    InternalServerError(Box<dyn DowncastableError>),
    StatusCodeError {
        code: StatusCode,
        message: String,
    },
}

This type facilitates propagation of both internal server errors and status code errors. The former take place when something goes wrong in the backend that isn’t due to user error but nonetheless prevents a normal response (e.g. error contacting the database, a file on the backend server was not found). The latter is when an error takes place in a function that corresponds to a particular response to the user, for example if a function is called to get a row from a database that does not exist a StatusCodeError variant may be emitted with a 404 Not Found, thus allowing the caller to simply propogate this error via ? to the route and thus to the user.
