Function tokio::io::split

pub fn split<T>(stream: T) -> (ReadHalf<T>, WriteHalf<T>) where
    T: AsyncRead + AsyncWrite, 

This is supported on feature="io-util" only.

Splits a single value implementing AsyncRead + AsyncWrite into separate AsyncRead and AsyncWrite handles.

To restore this read/write object from its ReadHalf and WriteHalf use unsplit.
