Enum MemoryBackend 

pub enum MemoryBackend {
    InMemory(InMemory),
    Sqlite(SqliteMemory<NoEmbedder>),
}

Memory backend selected from configuration.

Delegates all Memory trait methods to the inner variant.

Variants

InMemory(InMemory)

Volatile in-memory store.

Sqlite(SqliteMemory<NoEmbedder>)

SQLite-backed persistent store (no embedder).

Implementations

impl MemoryBackend

pub fn in_memory() -> Self

Create an in-memory backend.

pub fn sqlite(path: &str) -> Result<Self>

Create a SQLite backend at the given path.

Trait Implementations

impl Memory for MemoryBackend

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 all entries into a string for system prompt injection.
