Struct zmq::PollItem

#[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.
