[−][src]Trait gotham::handler::MapHandlerErrorFuture

pub trait MapHandlerErrorFuture {
    fn map_err_with_status(
        self, 
        status_code: StatusCode
    ) -> MapErrWithStatus<Self>
    where
        Self: Sized;
}

This trait allows you to convert a Result's Err case into a handler error with the given status code. This is handy if you want to specify the status code but still use the ? shorthand.

fn handler() -> impl Future<Output = Result<(), HandlerError>> {
	let result = async { Err(anyhow!("just a test")) };
	result.map_err_with_status(StatusCode::IM_A_TEAPOT)
}

let response = block_on(handler());
assert_eq!(response.map_err(|err| err.status()), Err(StatusCode::IM_A_TEAPOT));

Required methods

`fn map_err_with_status(self, status_code: StatusCode) -> MapErrWithStatus<Self> where Self: Sized,`

Equivalent of map_err(|err| HandlerError::from(err).with_status(status_code)).
