Struct PgVectorStore 

pub struct PgVectorStore { /* private fields */ }

pgvector adapter for PostgreSQL with the vector extension.

Implementations

impl PgVectorStore

pub fn new( connection_string: impl Into<String>, table_name: impl Into<String>, dimension: usize, ) -> Self

Create a new pgvector adapter in stub mode.

The vector column defaults to "embedding". Use Self::with_vector_column to override.

pub fn with_vector_column(self, column: impl Into<String>) -> Self

Override the vector column name (default "embedding").

pub fn table_name(&self) -> &str

Return the configured table name.

pub fn vector_column(&self) -> &str

Return the configured vector column name.

pub fn dimension(&self) -> usize

Return the configured dimension.

pub fn connection_string(&self) -> &str

Return the configured connection string.

pub fn render_insert_sql(&self) -> String

Render a stub SQL INSERT statement for documentation / debug.

This does NOT execute anything — it is a helper that makes the underlying SQL shape visible for tests and for users planning a real driver integration.

pub fn render_search_sql(&self) -> String

Render a stub SQL SELECT statement for cosine similarity search.

Trait Implementations

impl VectorStore for PgVectorStore

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

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

Insert a memory entry.

fn search<'life0, 'life1, 'async_trait>( &'life0 self, query_embedding: &'life1 [f32], top_k: usize, session_filter: Option<Uuid>, ) -> Pin<Box<dyn Future<Output = ArgentorResult<Vec<SearchResult>>> + Send + 'async_trait>>

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

Search for the top-k most similar entries to a query embedding.

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

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

Delete a memory entry by ID.

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

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

List all entries (optionally filtered by session).

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

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

Count entries.
