Enum NoticeChanges 

pub enum NoticeChanges {
    Detailed {
        entries: Vec<ChangeEnvelope>,
    },
    Ids {
        entries: Vec<ChangeEnvelope>,
    },
    Counts {
        counts: BTreeMap<String, usize>,
        by_change: NoticeByChange,
        self_inform: String,
    },
}

The size-graceful body of a MemChangedNotice. Internally tagged on mode so a caller decodes one stable shape and branches on the discriminator — no request-shape-dependent polymorphism.

The detailed and ids tiers carry ChangeEnvelopes — the exact per-entity shape memstead_changes_since emits (same action vocabulary, from_id / to_id on renames). Sharing the type is the point: an agent that follows the notice’s self_inform to memstead_changes_since decodes one shape on both surfaces, and the two delta representations cannot drift apart in vocabulary or richness.

Variants

Detailed

Small delta — full per-entity ChangeEnvelopes with title / entity_type enrichment.

Fields

entries: Vec<ChangeEnvelope>

Ids

Medium delta — every changed entity inline as a ChangeEnvelope with title / entity_type stripped. The id list (and a rename’s from_id / to_id) stays complete; only rich detail is dropped once the delta exceeds [NOTICE_DETAILED_MAX].

Fields

entries: Vec<ChangeEnvelope>

Counts

Mass change — counts by type and by change-kind, plus the memstead_changes_since(since=<from_head>) instruction for the full delta. counts keys are entity types (omitted for envelopes whose type the store couldn’t resolve, e.g. removed).

Fields

counts: BTreeMap<String, usize>

by_change: NoticeByChange

self_inform: String
