Struct zookeeper_client::PersistentWatcher

source · 
pub struct PersistentWatcher { /* private fields */ }
Expand description

Watcher for persistent and recursive watch.

Implementations§

source§

impl PersistentWatcher

source

pub async fn changed(&mut self) -> WatchedEvent

Waits for next event which could be node event or session activities.

Panics

Panic after terminal session event received.

source

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

Removes this watcher.

Cautions

It is a best effect as ZooKeper (ZOOKEEPER-4472) does not support persistent watch removing individually.
