PollFd

compio::net

Struct PollFd 

pub struct PollFd<T>(/* private fields */)
where
    T: AsFd;
Available on crate feature net only.
Expand description

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

Implementations§

§

impl<T> PollFd<T>
where T: AsFd,

pub fn new(source: T) -> Result<PollFd<T>, Error>

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

§

impl<T> PollFd<T>
where T: AsFd + 'static,

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

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

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

Wait for connect readiness.

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

Wait for read readiness.

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

Wait for write readiness.
