Trait SubscriptionDispatcher
pub trait SubscriptionDispatcher:
Clone
+ Send
+ Sync
+ 'static {
// Required method
fn open(
&self,
request: SubscriptionOpen,
) -> impl Future<Output = Result<Pin<Box<dyn Stream<Item = Result<Value, CratestackError>> + Send>>, CratestackError>> + Send;
}Expand description
Opens subscriptions by op id. Implemented by generated code (one impl per schema); called by every subscription binding.
Shaped like crate::AuthProvider: implement open as a plain
async fn. Returning Err refuses the subscription before the binding
tells the client it is ready, so policy refusals and setup failures
(“room not found”) never look like a mid-stream error.
Required Methods§
fn open( &self, request: SubscriptionOpen, ) -> impl Future<Output = Result<Pin<Box<dyn Stream<Item = Result<Value, CratestackError>> + Send>>, CratestackError>> + Send
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
