Required Associated Types

type ChainTipChangeStream: Stream<Item = Result<BlockHashAndHeight, Status>> + Send + 'static

Server streaming response type for the ChainTipChange method.

type NonFinalizedStateChangeStream: Stream<Item = Result<BlockAndHash, Status>> + Send + 'static

Server streaming response type for the NonFinalizedStateChange method.

type MempoolChangeStream: Stream<Item = Result<MempoolChangeMessage, Status>> + Send + 'static

Required Methods

fn chain_tip_change<'life0, 'async_trait>( &'life0 self, request: Request<Empty>, ) -> Pin<Box<dyn Future<Output = Result<Response<Self::ChainTipChangeStream>, Status>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Notifies listeners of chain tip changes

fn non_finalized_state_change<'life0, 'async_trait>( &'life0 self, request: Request<Empty>, ) -> Pin<Box<dyn Future<Output = Result<Response<Self::NonFinalizedStateChangeStream>, Status>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Notifies listeners of new blocks in the non-finalized state.
