Expand description

Generated trait containing gRPC methods that should be implemented for use with CommandHandlerServiceServer.

Required Methods§

Source

fn handle<'life0, 'async_trait>( &'life0 self, request: Request<ContextualCommand>, ) -> Pin<Box<dyn Future<Output = Result<Response<BusinessResponse>, Status>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Process command and return business response (events or revocation request)

Source

fn replay<'life0, 'async_trait>( &'life0 self, request: Request<ReplayRequest>, ) -> Pin<Box<dyn Future<Output = Result<Response<ReplayResponse>, Status>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Replay events to compute state (for conflict detection) Optional: only needed if aggregate supports MERGE_COMMUTATIVE

Implementors§
