pub struct HandlerError { /* private fields */ }
Expand description

Describes an error which occurred during handler execution, and allows the creation of a HTTP Response.

Implementations

Returns the HTTP status code associated with this HandlerError.

Sets the HTTP status code of the response which is generated by the IntoResponse implementation.

fn handler(state: State) -> Pin<Box<HandlerFuture>> {
    // It's OK if this is bogus, we just need something to convert into a `HandlerError`.
    let io_error = std::io::Error::last_os_error();

    let handler_error = HandlerError::from(io_error).with_status(StatusCode::IM_A_TEAPOT);

    future::err((state, handler_error)).boxed()
}

let test_server = TestServer::new(|| Ok(handler)).unwrap();
let response = test_server
    .client()
    .get("http://example.com/")
    .perform()
    .unwrap();
assert_eq!(response.status(), StatusCode::IM_A_TEAPOT);
