Struct TraceStore 

pub struct TraceStore { /* private fields */ }

SQLite-backed trace store. Cheap to clone — wraps an Arc<Mutex<Connection>>.

Implementations

impl TraceStore

pub fn open(path: PathBuf) -> Result<Self>

Open (or create) the trace store at a specific path.

pub fn open_in_memory() -> Result<Self>

Open an in-memory store (tests / ephemeral use).

pub async fn open_span( &self, conversation_id: &str, kind: &str, name: &str, args_hash: Option<&str>, session_id: Option<&str>, ) -> Result<String>

Open a span (tool-call or model-call). Returns the new span id.

args_hash should be Some(hash_args(&input)) for tool-call spans and None for model-call spans.

pub async fn close_span(&self, span_id: &str, error: Option<&str>) -> Result<()>

Close a span — set ended_at and optionally record an error.

pub async fn get_spans(&self, conversation_id: &str) -> Result<Vec<Span>>

Return all spans for a run in ascending seq order.

Trait Implementations

impl Clone for TraceStore

fn clone(&self) -> TraceStore

Returns a duplicate of the value.

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

Performs copy-assignment from source.
