Struct ParticipantAckCommit 

pub struct ParticipantAckCommit { /* private fields */ }

Atomic zero-debt participant-ack commit.

The cursor update is intentionally opaque. Only Self::apply_to can validate and apply it to a LiveMember, while Self::outcome exposes the crate-owned wire success for persistence and response encoding.

Implementations

impl ParticipantAckCommit

pub const fn outcome(&self) -> &AckCommitted

Borrows the exact committed wire outcome.

pub const fn observer_progress_projection(&self) -> ObserverProgressProjection

Projects the exact committed ack boundary into hard observer progress.

pub fn apply_to<F>( self, member: &mut LiveMember<F>, ) -> Result<AckCommitted, ParticipantAckCommitError>

Applies this commit to either its exact old cursor or its already-written resulting cursor.

Replaying after a crash is idempotent: the old prestate advances once, while the exact new prestate returns the same AckCommitted without a second mutation.

Errors

Returns ParticipantAckCommitError if the supplied member differs in conversation, participant, generation, or cursor prestate.
