shared_failure

本包旨在提供一个方便且轻量级的方式来克隆错误并在线程边界间共享。

它设计用于与failure包一起使用。

示例

let custom_error = std::io::Error::new(std::io::ErrorKind::Other, "oh no!");

let shared_error = SharedFailure::from_fail(custom_error);

// can be cloned, even though std::io::Error does not impl Clone
let cloned_error = shared_error.clone();

assert_eq!(shared_error.to_string(), "oh no!");
assert_eq!(cloned_error.to_string(), "oh no!");

assert_eq!(shared_error.downcast_ref::<std::io::Error>().unwrap().kind(),
    std::io::ErrorKind::Other);
