Enum highnoon::Error

pub enum Error {
    Http(Response),
    Internal(Error),
}

Error type expected to be returned by endpoints.

It can represent an HTTP level error which is useful for helper functions that wish to cause an early return from a handler (using the question mark operator). It can also represent any other kind of error (using the anyhow::Error type). These errors are logged (if you enable the logging filter) and converted to a 500 Internal Server Error with no other details.

HTTP level error should be created with the http methods (which accepts a Responder rather than just Response) and Internal errors should be created with the From/Into implementation.

Variants

Http(Response)

An error that should get returned to the client

Internal(Error)

Internal errors, reported as 500 Internal Server Error and logged locally

Implementations

impl Error

pub fn http(resp: impl Responder) -> Self

Create an Error from a Responder - the Responder will be converted to a response and returned to the HTTP Client exactly the same way as an Result::Ok would be. This is useful in conjunction with the ? operator for early returns.

pub fn bad_request(resp: impl Responder) -> Self

Create a 400 Bad Request Error from a Responder - this method is similar to Error::http but it also sets the status code

impl<E> From<E> for Errorwhere
    E: Into<Error>,

fn from(e: E) -> Self
