Struct JsonlSessionStore 

pub struct JsonlSessionStore { /* private fields */ }

Persistent SessionStore writing one JSONL file per session.

Each session <id> lives in <dir>/<id>.jsonl: line 1 is the SessionMeta header as JSON, and every following line is one SessionEntry as JSON. Appends open the file in append mode, write a single line, and flush immediately, so a crash loses at most the in-flight entry. When loading, a partially written final line (a crash-truncated tail without a trailing newline) is discarded and truncated from the file, so later appends stay line-aligned instead of fusing onto the fragment; an unparseable complete line is an error.

Implementations

impl JsonlSessionStore

pub fn new(dir: impl Into<PathBuf>) -> Self

Creates a store rooted at dir. The directory is created lazily on the first SessionStore::create call.

Trait Implementations

impl Clone for JsonlSessionStore

fn clone(&self) -> JsonlSessionStore

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for JsonlSessionStore

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl SessionStore for JsonlSessionStore

fn create<'life0, 'async_trait>( &'life0 self, meta: SessionMeta, ) -> Pin<Box<dyn Future<Output = Result<String, AgentError>> + Send + 'async_trait>>

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

Creates a new session from its header and returns the session id.

fn append<'life0, 'life1, 'async_trait>( &'life0 self, session_id: &'life1 str, entry: SessionEntry, ) -> Pin<Box<dyn Future<Output = Result<(), AgentError>> + Send + 'async_trait>>

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

Appends one entry to an existing session.

fn load<'life0, 'life1, 'async_trait>( &'life0 self, session_id: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<Vec<SessionEntry>, AgentError>> + Send + 'async_trait>>

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

Loads all entries of a session in append order.

fn list<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Vec<SessionMeta>, AgentError>> + Send + 'async_trait>>

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

Lists the headers of all sessions in the store.
