}

Configuration for constructing a Stateful application.

Fields

application: A

The inner application that drives state transitions.

db_config: <A::Databases as DatabaseSet<E>>::Config

Configuration used to construct the database set.

input_provider: A::InputProvider

Source of input (e.g. transactions) passed to the application on propose.

marshal: Mailbox<S, V>

Marshal mailbox used for startup anchoring and lazy recovery.

max_pending_acks: NonZeroUsize

Marshal ack window used by the provided marshal mailbox.

This must match the marshal config used to construct Self::marshal.

mailbox_size: NonZeroUsize

Capacity of the stateful actor mailbox channel.

plan: SyncPlan<E, S, V>

Startup plan loaded via SyncPlan::init, optionally augmented with a finalized floor via SyncPlan::with_floor. Carries the durable metadata handle and the startup decision shared with marshal.

resolvers: R

Resolver(s) for state sync fetches and post-bootstrap serving.

sync_config: SyncEngineConfig

Sync engine tuning knobs.
