Struct PollFd

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

struct pollfd—File descriptor and flags for use with poll.

Implementations

impl<'fd> PollFd<'fd>

pub fn new<Fd: AsFd>(fd: &'fd Fd, events: PollFlags) -> Self

Constructs a new PollFd holding fd and events.

pub fn set_fd<Fd: AsFd>(&mut self, fd: &'fd Fd)

Sets the contained file descriptor to fd.

pub fn clear_revents(&mut self)

Clears the ready events.

pub fn from_borrowed_fd(fd: BorrowedFd<'fd>, events: PollFlags) -> Self

Constructs a new PollFd holding fd and events.

This is the same as new, but can be used to avoid borrowing the BorrowedFd, which can be tricky in situations where the BorrowedFd is a temporary.

pub fn revents(&self) -> PollFlags

Returns the ready events.
