[−][src]Struct update_channel::Updater
The updater half of the update channel.
You can update the shared value with Updater::update.
This doesn't mean that receivers directly hold the new value
Implementations
impl<T> Updater<T>[src]
pub fn has_receiver(&self) -> bool[src]
Checks if at least one receiver exists
pub fn update(&self, value: T) -> Result<(), UpdateError<T>>[src]
Updates the value currently saved in the channel. A receiver can then call update in order to check the latest value and write it into its buffer. If either the RwLock is poisoned, or no receiver exists an UpdateError holding the value will be returned.
