Struct Empty
struct Empty { ... }Empty ignores any data written via AsyncWrite, and will always be empty
(returning zero bytes) when read via AsyncRead.
This struct is generally created by calling empty. Please see
the documentation of empty() for more details.
This is an asynchronous version of std::io::empty.
