Struct TraceStore 

pub struct TraceStore { /* private fields */ }

Thread-safe store of recent request traces.

Bounded to capacity entries; oldest entries are evicted when the cap is reached. All public methods take &self to allow sharing across tasks via Arc<TraceStore>.

Implementations

impl TraceStore

pub fn new(capacity: usize) -> Self

Create a store with the given capacity.

pub fn upsert(&self, trace: RequestTrace)

Insert or update a trace. Evicts the oldest entry when at capacity.

pub fn stage_started(&self, request_id: &str, stage_index: usize)

Record a stage start event.

pub fn stage_finished( &self, request_id: &str, stage_index: usize, success: bool, )

Record a stage finish event.

pub fn get(&self, request_id: &str) -> Option<RequestTrace>

Look up a trace by request id.

pub fn known_ids(&self) -> Vec<String>

Return a list of all known request ids (newest last).
