Struct StubVectorStore 

pub struct StubVectorStore;

Stub Vector Store 实现

所有方法均返回 Unsupported 错误，仅在未启用 real-pg feature 时 提供一个可编译的占位实现。

Implementations

impl StubVectorStore

pub fn new() -> Self

Trait Implementations

impl Default for StubVectorStore

fn default() -> Self

Returns the “default value” for a type.

impl PgVectorStore for StubVectorStore

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,
