Trait gotham::prelude::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)).
