Struct Probe

Source

pub struct Probe<E, S, D, V, T, P, B>where
    E: Spawner + CryptoRng + Clock + Metrics,
    S: Scheme<V::Commitment, PublicKey = P>,
    D: Provider<Scope = Epoch, Scheme = S>,
    V: Variant,
    T: Strategy,
    P: PublicKey,
    B: Blocker<PublicKey = P>,
{ /* private fields */ }

Expand description

Discovers a sync floor by adopting the highest finalization from a peer sample.

The actor is a two-phase state machine. It starts in discovery, waits until a subscriber needs a floor, then solicits and samples peers’ finalizations without answering any of its own. Once a marshal is attached, it hands off to service, answering peers’ requests from that marshal and never issuing outbound requests. A source node that never needed a floor attaches a marshal without consuming one and enters service without soliciting peers.
