}Expand description
Transport abstraction for cross-cache invalidation.
Implement this trait for a real transport such as Postgres LISTEN/NOTIFY, Redis Pub/Sub, NATS, or an application-specific message bus. HydraCache only requires fire-and-forget invalidation messages; values are never replicated.
Required Methods§
Sourcefn publish<'life0, 'async_trait>(
&'life0 self,
message: CacheInvalidationMessage,
) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
fn publish<'life0, 'async_trait>(
&'life0 self,
message: CacheInvalidationMessage,
) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
Publish an invalidation message.
Sourcefn subscribe(&self) -> Box<dyn CacheInvalidationReceiver>
fn subscribe(&self) -> Box<dyn CacheInvalidationReceiver>
Subscribe to invalidation messages.
Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
