Struct gio::PollableInputStream
source · #[repr(transparent)]pub struct PollableInputStream { /* private fields */ }
Expand description
PollableInputStream
is implemented by GInputStreams
that
can be polled for readiness to read. This can be used when
interfacing with a non-GIO API that expects
UNIX-file-descriptor-style asynchronous I/O rather than GIO-style.
