Struct SqliteMemory 

pub struct SqliteMemory<E: Embedder> { /* private fields */ }

SQLite-backed memory store with optional embedding support.

Implementations

impl<E: Embedder> SqliteMemory<E>

pub fn open(path: impl AsRef<Path>) -> Result<Self>

Open or create a SQLite database at the given path.

pub fn in_memory() -> Result<Self>

Create an in-memory database (useful for testing).

pub fn with_embedder(self, embedder: E) -> Self

Attach an embedder for vector search.

pub fn store_with_metadata( &self, key: &str, value: &str, metadata: Option<&Value>, embedding: Option<&[f32]>, ) -> Result<()>

Store a key-value pair with optional metadata and embedding.

pub fn get_entry(&self, key: &str) -> Option<MemoryEntry>

Get a full MemoryEntry for a key.

Trait Implementations

impl<E: Embedder> Memory for SqliteMemory<E>

fn get(&self, key: &str) -> Option<String>

Get the value for a key (owned).

fn entries(&self) -> Vec<(String, String)>

Get all key-value pairs (owned).

fn set( &self, key: impl Into<String>, value: impl Into<String>, ) -> Option<String>

Set (upsert) a key-value pair. Returns the previous value if the key existed.

fn remove(&self, key: &str) -> Option<String>

Remove a key. Returns the removed value if it existed.

fn store( &self, key: impl Into<String> + Send, value: impl Into<String> + Send, ) -> impl Future<Output = Result<()>> + Send

Store a key-value pair (async). Default delegates to set.

fn recall( &self, query: &str, options: RecallOptions, ) -> impl Future<Output = Result<Vec<MemoryEntry>>> + Send

Search for relevant entries (async). Default returns empty.

fn compile_relevant(&self, query: &str) -> impl Future<Output = String> + Send

Compile relevant entries for a query (async). Default delegates to compile.

fn compile(&self) -> String

Compile memory into a string for system prompt injection.
