Trait pal_async::fd::PollFdReady

pub trait PollFdReady:

    // Required methods
    fn poll_fd_ready(
        &mut self,
        cx: &mut Context<'_>,
        slot: InterestSlot,
        events: PollEvents,
    ) -> Poll<PollEvents>;
    fn clear_fd_ready(&mut self, slot: InterestSlot);
}

A trait for polling file descriptor readiness.

Required Methods

fn poll_fd_ready( &mut self, cx: &mut Context<'_>, slot: InterestSlot, events: PollEvents, ) -> Poll<PollEvents>

Polls a file descriptor for readiness.

fn clear_fd_ready(&mut self, slot: InterestSlot)

Clears cached socket readiness so that the next call to poll_socket_ready will poll the OS again.

With the epoll driver, this may not be sufficient for poll_fd_ready to complete again–the caller must also ensure that the kernel has seen a transition to a not-ready state (e.g. by seeing EAGAIN returned from read).
