Struct ChatMessageHistory 

pub struct ChatMessageHistory { /* private fields */ }

MemoryStore implementation backed by any Store.

Messages are stored under namespace ["memory", "{session_id}"] with key "messages". Summaries (used by summary strategies) are stored under the same namespace with key "summary".

This replaces the old InMemoryStore (in-memory only) and FileChatMessageHistory (file-only) with a single implementation that works with any Store backend (InMemoryStore, FileStore, RedisStore, etc.).

Implementations

impl ChatMessageHistory

pub fn new(store: Arc<dyn Store>) -> Self

Create a new ChatMessageHistory backed by the given store.

pub async fn get_summary( &self, session_id: &str, ) -> Result<Option<String>, SynapticError>

Get the summary for a session (used by summary memory strategies).

pub async fn set_summary( &self, session_id: &str, summary: &str, ) -> Result<(), SynapticError>

Set the summary for a session (used by summary memory strategies).

pub fn store(&self) -> &Arc<dyn Store>

Return a reference to the underlying store.
