Defines the state / environment of a SpacetimeDB node from the PoV of the client API.

Types returned here should be considered internal state and never be surfaced to the API.

Required Associated Types

type JwtAuthProviderT: JwtAuthProvider

Required Methods

fn gather_metrics(&self) -> Vec<MetricFamily>

fn client_actor_index(&self) -> &ClientActorIndex

fn jwt_auth_provider(&self) -> &Self::JwtAuthProviderT

fn leader<'life0, 'async_trait>( &'life0 self, database_id: u64, ) -> Pin<Box<dyn Future<Output = Result<Option<Host>>> + Send + 'async_trait>>

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

Return the leader Host of database_id.

Returns None if the current leader is not hosted by this node. The Host is spawned implicitly if not already running.

fn module_logs_dir(&self, replica_id: u64) -> ModuleLogsDir
