Struct LongTermMemory 

pub struct LongTermMemory { /* private fields */ }

Long-term Memory 实现

使用向量数据库存储，支持语义检索。

Implementations

impl LongTermMemory

pub fn new(retriever: Option<Arc<dyn RetrieverEngine>>) -> Self

Trait Implementations

impl Default for LongTermMemory

fn default() -> Self

Returns the “default value” for a type.

impl MemoryStore for LongTermMemory

fn tier(&self) -> MemoryTier

记忆层级

fn store<'life0, 'async_trait>( &'life0 self, entry: MemoryEntry, ) -> Pin<Box<dyn Future<Output = Layer3Result<String>> + Send + 'async_trait>>

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

存储记忆条目

fn get<'life0, 'life1, 'async_trait>( &'life0 self, id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Layer3Result<Option<MemoryEntry>>> + Send + 'async_trait>>

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

获取记忆条目

fn delete<'life0, 'life1, 'async_trait>( &'life0 self, id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Layer3Result<bool>> + Send + 'async_trait>>

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

删除记忆条目

fn query<'life0, 'life1, 'async_trait>( &'life0 self, query: &'life1 MemoryQuery, ) -> Pin<Box<dyn Future<Output = Layer3Result<Vec<MemoryEntry>>> + Send + 'async_trait>>

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

查询记忆（按内容搜索）

fn list<'life0, 'async_trait>( &'life0 self, limit: Option<usize>, ) -> Pin<Box<dyn Future<Output = Layer3Result<Vec<MemoryEntry>>> + Send + 'async_trait>>

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

列出所有记忆（按时间排序）

fn clear<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Layer3Result<usize>> + Send + 'async_trait>>

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

清空该层所有记忆

fn count<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Layer3Result<usize>> + Send + 'async_trait>>

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