Struct QueueTimer 

pub struct QueueTimer<'a> { /* private fields */ }

Thin wrapper for recording queue-wait latency around one await point.

Implementations

impl QueueTimer<'_>

pub fn with_depth_at_start(self, depth_at_start: u64) -> Self

Sets the queue depth sample captured at wait start.

pub async fn await_on<Fut, T>(self, fut: Fut) -> T

where Fut: Future<Output = T>,

Awaits fut, records queue wait duration, and returns the original output.

Queue events are interpreted as application-level wait evidence (a lead, not proof). Record these around bounded resources to help separate queueing pressure from slow downstream stage time.

Trait Implementations

impl<'a> Debug for QueueTimer<'a>

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

Formats the value using the given formatter.
