utils_atomics::channel::once

Struct Receiver

Source 
pub struct Receiver<T> { /* private fields */ }
Available on crate feature alloc only.
Expand description

A channel receiver that can only receive a single value

Implementations§

Source§

impl<T> Receiver<T>

Source

pub fn wait(self) -> Option<T>

Blocks the current thread until the value is received. If Sender is dropped before it sends the value, this method returns None.

Source

pub fn wait_timeout(&self, dur: Duration) -> Result<Option<T>, Timeout>

Available on crate feature std only.

Blocks the current thread until the value is received. If Sender is dropped before it sends the value, this method returns None.

§Errors

This method returns an error if the wait didn’t conclude before the specified duration
