[−][src]Struct futures::io::AllowStdIo
A simple wrapper type which allows types which implement only
implement std::io::Read or std::io::Write
to be used in contexts which expect an AsyncRead or AsyncWrite.
If these types issue an error with the kind io::ErrorKind::WouldBlock,
it is expected that they will notify the current task on readiness.
Synchronous std types should not issue errors of this kind and
are safe to use in this context. However, using these types with
AllowStdIo will cause the event loop to block, so they should be used
with care.
