Struct Actor 

Source 
pub struct Actor<B: Block, R: Rng + Spawner + Metrics + Clock + GClock + Storage, V: Variant, P: PublicKey, Z: Coordinator<PublicKey = P>> { /* private fields */ }
Expand description

The Actor is responsible for receiving uncertified blocks from the broadcast mechanism, receiving notarizations and finalizations from consensus, and reconstructing a total order of blocks.

The actor is designed to be used in a view-based model. Each view corresponds to a potential block in the chain. The actor will only finalize a block if it has a corresponding finalization.

The actor also provides a backfill mechanism for missing blocks. If the actor receives a finalization for a block that is ahead of its current view, it will request the missing blocks from its peers. This ensures that the actor can catch up to the rest of the network if it falls behind.
