Struct InMemoryHistoryStore 

pub struct InMemoryHistoryStore { /* private fields */ }

Volatile HistoryStore kept entirely in process memory. Intended for tests and short-lived sessions where durable persistence is not required.

Panics

save / load .expect() on an internal Mutex — they only panic if the lock is poisoned by a previous panic in another task that held the guard.

Implementations

impl InMemoryHistoryStore

pub fn new() -> InMemoryHistoryStore

Build an empty store. Equivalent to InMemoryHistoryStore::default.

Trait Implementations

impl Default for InMemoryHistoryStore

fn default() -> InMemoryHistoryStore

Returns the “default value” for a type.

impl HistoryStore for InMemoryHistoryStore

type Error = Infallible

Error type surfaced from save / load. Use std::convert::Infallible when the implementation cannot fail (see InMemoryHistoryStore).

fn save<'life0, 'life1, 'async_trait>( &'life0 self, snapshot: &'life1 ConversationSnapshot, ) -> Pin<Box<dyn Future<Output = Result<(), <InMemoryHistoryStore as HistoryStore>::Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, InMemoryHistoryStore: 'async_trait,

Persist snapshot so a later load returns it. Implementations should treat this as an overwrite — the façade passes the full updated ConversationSnapshot every time rather than diffing.

fn load<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Option<ConversationSnapshot>, <InMemoryHistoryStore as HistoryStore>::Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, InMemoryHistoryStore: 'async_trait,

Return the most recently persisted snapshot, or Ok(None) when the store has never been written to. Returning Ok(None) lets callers default-init the conversation on first run instead of special-casing a missing payload.
