Expand description

Trait defining a generic database listener.

Required Methods§

Source

fn start<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<(Arc<Mutex<Receiver<Value>>>, JoinHandle<()>), DBListenerError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Starts the listener and returns a receiver channel for event notifications.

§Returns

A Result containing a tuple of an Arc<Mutex<Receiver<Value>>> and a JoinHandle<()>, or an error if the listener fails to start.

Source

fn stop<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<(), DBListenerError>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Stops the database listener gracefully.

§Returns

A Result indicating success or failure.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
