Trait CanonStateSubscriptions 

pub trait CanonStateSubscriptions: Send + Sync {
    type Primitives: NodePrimitives;

    // Required method
    fn subscribe_to_canonical_state(
        &self,
    ) -> CanonStateNotifications<Self::Primitives>;

    // Provided method
    fn canonical_state_stream(
        &self,
    ) -> CanonStateNotificationStream<Self::Primitives> { ... }
}

A type that allows to register chain related event subscriptions.

Required Associated Types

type Primitives: NodePrimitives

The node primitive types.

Required Methods

fn subscribe_to_canonical_state( &self, ) -> CanonStateNotifications<Self::Primitives>

Get notified when a new canonical chain was imported.

A canonical chain be one or more blocks, a reorg or a revert.

Provided Methods

fn canonical_state_stream( &self, ) -> CanonStateNotificationStream<Self::Primitives>

Convenience method to get a stream of CanonStateNotification.

Dyn Compatibility

This trait is dyn compatible.

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