Struct RequestTrace 

pub struct RequestTrace {
    pub request_id: String,
    pub entry_time: Instant,
    pub stages: [Option<StageRecord>; 5],
    pub complete: bool,
}

Complete lifecycle record for one request.

Fields

request_id: String

Unique identifier for the request.

entry_time: Instant

Wall-clock time when the request entered the pipeline.

stages: [Option<StageRecord>; 5]

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

Record the completion of a stage.

pub fn total_elapsed(&self) -> Duration

Total elapsed time from entry to now (or until Stream completed).
