Expand description

Creates a future which will read exactly enough bytes to fill buf, unless EOF is reached first. If a short read should be considered an error, use tokio::io::AsyncReadExt::read_exact instead.

The returned future will resolve to the number of bytes read.

In the case of an error the contents of the buffer are unspecified.
