Motivation
When appropriate, implement
AsRawFdandAsRawHandlefortokio_util::compat::Compat<T>, so this wrapper type can be used in contexts requiring them.I ran into this while trying to wrap tokio's
Stdin/Stdoutfor usage with the futures crate, while still being able to check if they're a tty with crossterm.Solution
A blanket impl passing AsRawFd/AsRawHandle through to the inner read/write type
