Struct PollItem

#[repr(C)]
pub struct PollItem<'a> { /* private fields */ }

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.

Implementations

impl<'a> PollItem<'a>

pub fn from_fd(fd: RawFd, events: PollEvents) -> PollItem<'a>

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)

Change the events to wait for.

pub fn get_revents(&self) -> PollEvents

Retrieve the events that occurred for this handle.

pub fn is_readable(&self) -> bool

Returns true if the polled socket has messages ready to receive.

pub fn is_writable(&self) -> bool

Returns true if the polled socket can accept messages to be sent without blocking.

pub fn is_error(&self) -> bool

Returns true if the polled socket encountered an error condition.

pub fn has_socket(&self, socket: &Socket) -> bool

Returns true if the polled socket is the given 0MQ socket.

pub fn has_fd(&self, fd: RawFd) -> bool

Returns true if the polled socket is the given file descriptor.
