[−][src]Module futures_util::io
IO
This module contains a number of functions for working with
AsyncRead
, AsyncWrite
, AsyncSeek
, and AsyncBufRead
types, including
the AsyncReadExt
, AsyncWriteExt
, AsyncSeekExt
, and AsyncBufReadExt
traits which add methods to the AsyncRead
, AsyncWrite
, AsyncSeek
,
and AsyncBufRead
types.
This module is only available when the io
and std
features of this
library is activated, and it is activated by default.
