Event

Struct Event 

Source
pub struct Event(/* private fields */);
Expand description

Opaque typed completion event.

Constructors validate each event’s local scalar shape. Edge transitions then consume the event and match its participant, binding, marker, range, and boundary against the exact stored predecessor. The private kind set is the frozen eight-kind register: marker and normal acknowledgements share CursorProgressed, while live and detached alternatives share LeaveCommitted; the convenience constructors do not invent occurrences.

Implementations§

Source§

impl Event

Source

pub const fn projection_completed(through_seq: DeliverySeq) -> Self

Records observer projection through an exact sequence.

Source

pub const fn compaction_completed( from_floor: DeliverySeq, through_seq: DeliverySeq, resulting_floor: DeliverySeq, ) -> Option<Self>

Records exact physical compaction and its resulting floor.

Source

pub const fn marker_appended( marker_delivery_seq: DeliverySeq, resulting_projection_through: DeliverySeq, ) -> Self

Records a preclaimed marker append that extends an OP suffix.

Source

pub const fn marker_delivered( participant_id: ParticipantId, binding_epoch: BindingEpoch, marker_delivery_seq: DeliverySeq, ) -> Self

Records final-emitter delivery of an exact marker to an exact epoch.

Source

pub const fn cursor_progressed( participant_id: ParticipantId, binding_epoch: BindingEpoch, previous_cursor: DeliverySeq, through_seq: DeliverySeq, resulting_floor: DeliverySeq, ) -> Option<Self>

Records a strictly advancing cumulative normal ack.

V1’s permanent participant id is the participant index, so the stored occurrence key is derived from participant_id rather than accepted as an independently forgeable value.

Source

pub const fn marker_acknowledged( participant_id: ParticipantId, binding_epoch: BindingEpoch, marker_delivery_seq: DeliverySeq, resulting_floor: DeliverySeq, ) -> Self

Records acceptance of one exact delivered marker, deriving its participant-index occurrence key from the permanent participant id.

Source

pub const fn binding_fate_observed( participant_id: ParticipantId, binding_epoch: BindingEpoch, resulting_floor: DeliverySeq, ) -> Self

Records exact binding fate and its measured floor effect.

Source

pub const fn live_leave_committed( participant_id: ParticipantId, binding_epoch: BindingEpoch, resulting_floor: DeliverySeq, ) -> Self

Records a live-bound Leave and its measured floor effect.

Source

pub const fn detached_leave_committed( participant_id: ParticipantId, resulting_floor: DeliverySeq, ) -> Self

Records a detached Leave and its measured floor effect.

Source

pub const fn fenced_recovery_committed( participant_id: ParticipantId, marker_delivery_seq: DeliverySeq, prior_binding_epoch: BindingEpoch, new_binding_epoch: BindingEpoch, resulting_floor: DeliverySeq, ) -> Self

Records exact fenced recovery into a new binding epoch.
