[−][src]Struct zmq::PollItem
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.
Methods
impl<'a> PollItem<'a>
[src]
pub fn from_fd(fd: RawFd, events: PollEvents) -> PollItem<'a>
[src]
Construct a PollItem from a non-0MQ socket, given by its file descriptor and the events that should be polled.
pub fn set_events(&mut self, events: PollEvents)
[src]
Change the events to wait for.
pub fn get_revents(&self) -> PollEvents
[src]
Retrieve the events that occurred for this handle.
pub fn is_readable(&self) -> bool
[src]
Returns true if the polled socket has messages ready to receive.
pub fn is_writable(&self) -> bool
[src]
Returns true if the polled socket can accept messages to be sent without blocking.
pub fn is_error(&self) -> bool
[src]
Returns true if the polled socket encountered an error condition.
