Expand description

Complete raw state for one participant-scoped nonzero-debt cursor episode.

Fields§

§conversation_id: ConversationId

Owning conversation.

§debt: WideResourceVector

Raw componentwise closure debt, validated nonzero during restoration.

§observer_progress: DeliverySeq

Durable hard-observer progress o.

§candidate_high_watermark: DeliverySeq

Candidate high watermark H'.

§current_floor: u128

Current durable floor F.

§cap_floor: u128

Current append-free class capacity floor.

§participants: Vec<BoundParticipantCursor>

Bound participant cursors keyed by their embedded permanent ids.

§facts: Vec<(CursorProgressKey, CursorProgressFact)>

Variable facts keyed by (participant_index, boundary).

Implementations§

impl CursorEpisodeRestore

pub fn restore(self) -> Result<NonzeroDebtCursorEpisode, StorageRestoreError>

Validates and rebuilds one cursor episode and all variable facts.

§Errors

Returns StorageRestoreError::CursorEpisode for an invalid floor, duplicate/unknown participant, duplicate fact, out-of-range boundary, or fact state inconsistent with the participant cursor.
