Struct WrapCancel 

pub struct WrapCancel<T: Clone, F> { /* private fields */ }

Wrapped future that is automatically cancelled when a shutdown is triggered.

If the wrapped future completes before the shutdown is triggered, the output of the original future is yielded as Ok(value).

If the shutdown is triggered before the wrapped future completes, the original future is dropped and the shutdown reason is yielded as Err(shutdown_reason).
