Struct CursorProgressMarker 

pub struct CursorProgressMarker { /* private fields */ }

Marker-backed cursor-progress witness.

This value has no public constructor. It is produced only by consuming an exact MarkerDelivery with its matching Event::marker_delivered. That makes the durable exact-epoch delivery fact required by the frozen contract a type-level precondition for detached credential recovery.

Implementations

impl CursorProgressMarker

pub const fn conversation_id(self) -> ConversationId

Returns the conversation inherited from the exact marker delivery.

pub const fn participant_id(self) -> ParticipantId

Returns the participant whose marker must be accepted.

pub const fn binding_epoch(self) -> BindingEpoch

Returns the exact epoch that received the marker.

pub const fn through_seq(self) -> DeliverySeq

Returns the required cumulative boundary.

pub const fn marker_delivery_seq(self) -> DeliverySeq

Returns the exact delivered marker.

pub const fn storage_description(self) -> StoredEdgeRestore

Describes this witness as the capsule that restores it.

Including the nested delivery predecessor, which restore requires to agree with the witness field for field, so it has no field of its own to supply.
