Struct AsyncFdReadyGuard 

pub struct AsyncFdReadyGuard<'a, T: AsFd> { /* private fields */ }

What a readiness wait of an AsyncFd found: the readiness, and the edge counts it is of, to clear with.

Implementations

impl<T: AsFd> AsyncFdReadyGuard<'_, T>

pub fn ready(&self) -> Ready

What may be ready.

pub fn clear_ready(&mut self)

The descriptor would block: the next wait lasts until the driver says it may be ready again.

pub fn clear_ready_matching(&mut self, ready: Ready)

Clears what of ready this guard holds.

pub fn retain_ready(&mut self)

Keeps the readiness: the next wait may answer at once.

pub fn get_inner(&self) -> &T

The descriptor.

impl<'a, T: AsFd> AsyncFdReadyGuard<'a, T>

pub fn try_io<R>( &mut self, f: impl FnOnce(&'a AsyncFd<T>) -> Result<R>, ) -> Result<Result<R>, TryIoError>

Runs f; if it answers WouldBlock, the readiness is cleared and Err(TryIoError) comes back, else Ok with what it answered.

Errors

TryIoError when f would block.

pub fn get_ref(&self) -> &'a AsyncFd<T>

The descriptor’s AsyncFd.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
