Struct fuchsia_async::net::EventedFd

impl<T> EventedFd<T>
where T: AsRawFd,

pub unsafe fn new(inner: T) -> Result<Self>

Creates a new EventedFd.

§Safety

The raw file descriptor returned from inner.as_raw_fd() must not be closed until the returned EventedFd is dropped.

pub fn poll_readable(&self, cx: &mut Context<'_>) -> Poll<Result<(), Status>>

Tests to see if this resource is ready to be read from. If it is not, it arranges for the current task to receive a notification when a “readable” signal arrives.

pub fn poll_writable(&self, cx: &mut Context<'_>) -> Poll<Result<(), Status>>

Tests to see if this resource is ready to be written to. If it is not, it arranges for the current task to receive a notification when a “writable” signal arrives.

pub fn as_ref(&self) -> &T

pub fn as_mut(&mut self) -> &mut T

pub fn need_read(&self, cx: &mut Context<'_>)

Arranges for the current task to receive a notification when a “readable” signal arrives.

pub fn need_write(&self, cx: &mut Context<'_>)

Arranges for the current task to receive a notification when a “writable” signal arrives.

pub fn clear(&self)

Clears all incoming signals.
