批量向量操作扩展 trait

提供一次调用处理多个查询/记录的能力,减少网络往返开销。

Required Methods§

批量搜索:一次提交多个查询向量

返回与查询数量相同的结果列表,每个结果为对应查询的 top_k 结果

Source

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

Source

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

仅返回 metadata 中包含指定 key=value 的记录

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
