pub fn copy<R, W>(reader: R, writer: W) -> Copy<R, W>where
R: AsyncRead,
W: AsyncWrite,Expand description
Creates a future which represents copying all the bytes from one object to another.
The returned future will copy all the bytes read from reader into the
writer specified. This future will only complete once the reader has hit
EOF and all bytes have been written to and flushed from the writer
provided.
On success the number of bytes is returned and the reader and writer are
consumed. On error the error is returned and the I/O objects are consumed as
well.
