ⓘImportant traits for Compat<R>fn compat(self) -> Compat<Self>
[src]
fn compat(self) -> Compat<Self>
Wraps an [AsyncRead
] in a compatibility wrapper that allows it to be used as a futures 0.1 / tokio-io 0.1 AsyncRead
. If the wrapped type implements [AsyncWrite
] as well, the result will also implement the futures 0.1 / tokio 0.1 AsyncWrite
trait. Read more
