pub struct InvalidationSubscriber { /* private fields */ }
Expand description

Handle for subscribing to invalidation messages

This spawns a background task that listens to Redis Pub/Sub and processes invalidation messages by calling the provided handler callback.

Implementations§

Source§

impl InvalidationSubscriber

Source

pub fn new(redis_url: &str, config: InvalidationConfig) -> Result<Self>

Create a new subscriber

§Arguments
  • redis_url - Redis connection URL
  • config - Invalidation configuration
§Errors

Returns an error if Redis client creation fails.

Source

pub fn stats(&self) -> InvalidationStats

Get a snapshot of current statistics

Source

pub fn start<F, Fut>(&self, handler: F) -> JoinHandle<()>
where F: Fn(InvalidationMessage) -> Fut + Send + Sync + 'static, Fut: Future<Output = Result<()>> + Send + 'static,

Start the subscriber background task

§Arguments
  • handler - Async function to handle each invalidation message
§Returns

Join handle for the background task

Source

pub fn shutdown(&self)

Signal the subscriber to shutdown
