Struct PollFd

pub struct PollFd<T: AsRawFd>(/* private fields */);

A wrapper for socket, providing functionalities to wait for readiness.

Implementations

impl<T: AsRawFd> PollFd<T>

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

Create PollFd without attaching the source. Ready-based sources need not to be attached.

impl<T: AsRawFd + 'static> PollFd<T>

pub async fn accept_ready(&self) -> Result<()>

Wait for accept readiness, before calling accept, or after accept returns WouldBlock.

pub async fn connect_ready(&self) -> Result<()>

Wait for connect readiness.

pub async fn read_ready(&self) -> Result<()>

Wait for read readiness.

pub async fn write_ready(&self) -> Result<()>

Wait for write readiness.
