MemoryToolkit

hirn_engine::tools

Struct MemoryToolkit 

Source 
pub struct MemoryToolkit { /* private fields */ }
Expand description

Agent-facing toolkit with 6 self-editing memory operations.

Each method validates input, enforces Cedar policies via the agent’s identity, and delegates to HirnDB. Designed to be the single abstraction layer between protocol adapters (MCP, gRPC) and the engine.

Implementations§

Source§

impl MemoryToolkit

Source

pub fn new(db: Arc<HirnDB>) -> Self

Create a new toolkit wrapping the given database.

Source

pub fn db(&self) -> &HirnDB

Access the underlying database (for advanced operations).

Source

pub async fn store( &self, agent_id: AgentId, request: StoreRequest, ) -> HirnResult<MemoryId>

Store a new memory with RPE-gated admission.

Validates content, enforces Action::Remember policy, then delegates to HirnDB::remember().

Source

pub async fn recall( &self, agent_id: AgentId, query: &str, options: RecallOptions, ) -> HirnResult<Vec<RecallRecord>>

Recall memories matching a natural-language query.

Uses RecallBuilder directly with proper agent identity for Cedar enforcement.

Source

pub async fn update( &self, agent_id: AgentId, request: UpdateRequest, ) -> HirnResult<()>

Update an existing memory’s content and/or metadata.

Enforces Action::Remember (writes require store permission).

Source

pub async fn delete(&self, agent_id: AgentId, id: MemoryId) -> HirnResult<()>

Soft-delete (archive) a memory.

Sets the archived flag. Does not permanently remove the record.

Create a graph edge between two memories.

Source

pub async fn introspect( &self, agent_id: AgentId, id: Option<MemoryId>, ) -> HirnResult<IntrospectionResult>

Return memory statistics and optionally graph neighborhood for a memory.
