Struct gotham::handler::HandlerError

source · [−]

pub struct HandlerError { /* private fields */ }

Expand description

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

Implementations

impl HandlerError

pub fn status(&self) -> StatusCode

Returns the HTTP status code associated with this HandlerError.

pub fn with_status(self, status_code: StatusCode) -> 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);
