Struct gio::PollableOutputStream

source ·
pub struct PollableOutputStream { /* private fields */ }
Expand description

GPollableOutputStream is implemented by OutputStreams that can be polled for readiness to write. This can be used when interfacing with a non-GIO API that expects UNIX-file-descriptor-style asynchronous I/O rather than GIO-style.

Some classes may implement GPollableOutputStream but have only certain instances of that class be pollable. If PollableOutputStreamExt::can_poll() returns false, then the behavior of other GPollableOutputStream methods is undefined.
