WatcherHandle

d_engine_core::watch

Struct WatcherHandle 

Source 
pub struct WatcherHandle { /* private fields */ }
Expand description

Handle for a registered watcher

When dropped, the watcher is automatically unregistered (if unregister_tx is Some).

Implementations§

Source§

impl WatcherHandle

Source

pub fn id(&self) -> u64

Get the unique identifier for this watcher

Source

pub fn key(&self) -> &Bytes

Get the key being watched

Source

pub fn receiver_mut(&mut self) -> &mut Receiver<WatchEvent>

Get a mutable reference to the receiver

Source

pub fn into_receiver(self) -> (u64, Bytes, Receiver<WatchEvent>)

Consume the handle and return the event receiver

Disables automatic unregistration. The watcher will remain active until the receiver is dropped (causing send failures that trigger cleanup).

Use this for long-lived streams (e.g., gRPC) where the receiver lifetime extends beyond the handle’s scope.
