Struct zmq::PollItem
[−]
[src]
#[repr(C)]pub struct PollItem<'a> { /* fields omitted */ }
Represents a handle that can be poll()ed.
This is either a reference to a 0MQ socket, or a standard socket.
Apart from that it contains the requested event mask, and is updated
with the occurred events after poll() finishes.
