Struct PollFd

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

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

Implementations§

Source§

impl<T: AsRawFd> PollFd<T>

Source

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

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

Source§

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

Source

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

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

Source

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

Wait for connect readiness.

Source

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

Wait for read readiness.

Source

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

Wait for write readiness.
