Struct MemoryBatchOps 

pub struct MemoryBatchOps { /* private fields */ }

内存版批量操作实现

包装 InMemoryVectorStore，提供批量操作能力。 同时实现 PgVectorStore 以保证类型可组合使用。

Implementations

impl MemoryBatchOps

pub fn new(store: InMemoryVectorStore) -> Self

pub fn from_new() -> Self

pub fn inner(&self) -> &InMemoryVectorStore

获取内部 store 引用

Trait Implementations

impl BatchOpsExt for MemoryBatchOps

fn batch_search<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, collection: &'life1 str, queries: &'life2 [Vec<f32>], top_k: usize, ) -> Pin<Box<dyn Future<Output = Result<Vec<Vec<SearchResult>>, VectorError>> + Send + 'async_trait>>

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

批量搜索：一次提交多个查询向量

fn batch_get<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, collection: &'life1 str, ids: &'life2 [String], ) -> Pin<Box<dyn Future<Output = Result<Vec<Option<VectorRecord>>, VectorError>> + Send + 'async_trait>>

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

批量获取：一次获取多个 id 的记录

fn search_with_filter<'life0, 'life1, 'life2, 'life3, 'life4, 'async_trait>( &'life0 self, collection: &'life1 str, query: &'life2 [f32], top_k: usize, filter_key: &'life3 str, filter_value: &'life4 Value, ) -> Pin<Box<dyn Future<Output = Result<Vec<SearchResult>, VectorError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait, 'life4: 'async_trait,

按元数据过滤搜索

impl PgVectorStore for MemoryBatchOps

委托实现 PgVectorStore，将所有调用转发给内部 store

fn create_collection<'life0, 'life1, 'async_trait>( &'life0 self, name: &'life1 str, dimension: usize, metric: Option<VectorMetric>, ) -> Pin<Box<dyn Future<Output = Result<(), VectorError>> + Send + 'async_trait>>

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

创建集合

fn delete_collection<'life0, 'life1, 'async_trait>( &'life0 self, name: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<(), VectorError>> + Send + 'async_trait>>

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

删除集合

fn insert<'life0, 'life1, 'async_trait>( &'life0 self, collection: &'life1 str, records: Vec<VectorRecord>, ) -> Pin<Box<dyn Future<Output = Result<(), VectorError>> + Send + 'async_trait>>

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

插入向量记录（upsert 语义：相同 id 会覆盖）

fn search<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, collection: &'life1 str, query: &'life2 [f32], top_k: usize, ) -> Pin<Box<dyn Future<Output = Result<Vec<SearchResult>, VectorError>> + Send + 'async_trait>>

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

相似度搜索

fn get<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, collection: &'life1 str, id: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<Option<VectorRecord>, VectorError>> + Send + 'async_trait>>

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

获取单个记录

fn delete<'life0, 'life1, 'async_trait>( &'life0 self, collection: &'life1 str, ids: Vec<String>, ) -> Pin<Box<dyn Future<Output = Result<u64, VectorError>> + Send + 'async_trait>>

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

删除记录

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

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