Struct LongTermMemory 

pub struct LongTermMemory { /* private fields */ }

Unbounded long-term memory with weighted-decay ranking.

Implementations

impl LongTermMemory

pub fn new() -> Self

Creates a store with default DecayWeights and LexicalScorer.

pub fn with_config( weights: DecayWeights, scorer: Arc<dyn SemanticScorer>, ) -> Self

Creates a store with explicit weights and scorer.

pub fn weights(&self) -> &DecayWeights

Ranking configuration.

Trait Implementations

impl Debug for LongTermMemory

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for LongTermMemory

fn default() -> Self

Returns the “default value” for a type.

impl MemoryStore for LongTermMemory

fn put<'life0, 'life1, 'async_trait>( &'life0 self, namespace: &'life1 str, item: MemoryItem, ) -> Pin<Box<dyn Future<Output = Result<(), MemoryError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Writes/updates an item in the namespace. Re-putting an existing key refreshes its content and access time.

fn get<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, namespace: &'life1 str, key: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<Option<MemoryItem>, MemoryError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Exact key lookup (None when absent). Counts as an access.

fn search<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, query: &'life1 MemoryQuery<'life2>, ) -> Pin<Box<dyn Future<Output = Result<Vec<MemoryHit>, MemoryError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Semantic recall, best score first, capped at query.k.

fn forget<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, namespace: &'life1 str, key: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<bool, MemoryError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Removes one entry; returns whether it existed.

fn clear_namespace<'life0, 'life1, 'async_trait>( &'life0 self, namespace: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<usize, MemoryError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Drops every entry in the namespace; returns the number removed.

fn len_namespace<'life0, 'life1, 'async_trait>( &'life0 self, namespace: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<usize, MemoryError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Number of entries stored under the namespace.
