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

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

Implementations§

source§

impl<'fd> PollFd<'fd>

source

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

Constructs a new PollFd holding fd and events.

source

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

Sets the contained file descriptor to fd.

source

pub fn clear_revents(&mut self)

Clears the ready events.

source

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.

source

pub fn revents(&self) -> PollFlags

Returns the ready events.
