Struct published_value::Waiter

pub struct Waiter<T>(_);

Waiter waits for a value that has been published by Publisher. A Waiter can be cloned and cloned instances all receive the same published value.

Methods

impl<T> Waiter<T>

pub fn wait_for_value(&self) -> &T

Wait for the published value and return an immutable reference to it.

pub fn try_get_value(&self) -> Option<&T>

Attempt to get an immutable reference to the value, and return None if the value has not been published yet. This is guaranteed to succeed if wait_for_value has previously returned.

pub fn into_value(self) -> Result<T, Waiter<T>>

Attempt to gain exclusive ownership of the underlying value. This will only succeed if a value has been published and this is the only Waiter remaining. Otherwise, an Err is returned with the same Waiter that was passed in.
