pub trait MapHandlerErrorFuture {
    // Required method
    fn map_err_with_status(

}
Expand description

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)
);
