#[must_use = "futures do nothing unless you `.await` or poll them"]pub struct Copy<'a, R: ?Sized, W: ?Sized> { /* fields omitted */ }

A future that asynchronously copies the entire contents of a reader into a writer.

This struct is generally created by calling copy. Please see the documentation of copy() for more details.
