Struct ScopeCounts

The unified database facade for MenteDB.

MenteDb coordinates storage, indexing, graph relationships, query parsing, context assembly, and cognitive subsystems into a single coherent API.

All internal state is protected by fine-grained locks, so every public method takes &self. This allows Arc<MenteDb> to be shared across threads without an external RwLock. Per-owner/type/scope memory counts, excluding hidden (internal working) tags, maintained incrementally so the dashboard scope tree and stats read them in O(1) rather than scanning every memory. String keys keep it JSON-persistable; it is grounded by a full recount only when no snapshot exists (owner and type are not otherwise indexed, so a recount costs a full load and must be avoided on the read path and on every open).

Fields

total: u64

Non-hidden memories in total.

global: u64

Memories with no owner (nil user and agent): the shared/global pool.

always: u64

Memories tagged scope:always.

by_type: HashMap<String, u64>

Count by memory type name (lowercased, anti_pattern normalized).

by_user: HashMap<String, u64>

Count by end-user owner (uuid string).

by_agent: HashMap<String, u64>

Count by agent owner (uuid string).

by_user_agent: HashMap<String, u64>

Count by "user_uuid|agent_uuid" pair.

by_project: HashMap<String, u64>

Count by project name (from scope:project: tags).

growth: HashMap<String, u64>

Count by creation month (YYYY-MM, UTC) for the growth timeline. A memory’s creation month never changes, so this is exact and maintained incrementally like the rest, giving the dashboard an O(1) growth chart and an exact “this month” figure without a scan.
