[−][src]Module futures::io
Asynchronous I/O.
This module is the asynchronous version of std::io
. It defines two
traits, AsyncRead
and
AsyncWrite
, which mirror the Read
and
Write
traits of the standard library. However, these traits integrate
with the asynchronous task system, so that if an I/O object isn't ready
for reading (or writing), the thread is not blocked, and instead the
current task is queued to be woken when I/O is ready.
In addition, the AsyncReadExt
and
AsyncWriteExt
extension traits offer a
variety of useful combinators for operating with asynchronous I/O
objects, including ways to work with them using futures, streams and
sinks.

Close |
A future used to fully close an I/O object. |

A type used to conditionally initialize buffers passed to |
IoVec |
A specialized byte slice type for performing vectored I/O operations. |
Read |
A future which can be used to easily read available number of bytes to fill a buffer. |
