Thresholds for Trace::diagnose. Start from Default and adjust fields.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

stop_gap_target: Duration

Longest acceptable stretch without a cancellation check. Default 10 ms.

report_gap_target: Duration

Longest acceptable stretch without a report. Default 50 ms.

callback_budget: Duration

Longest acceptable callback. Default 10 ms.

callback_interval_target: Duration

Longest acceptable time between two runs of one callback. Default 10 ms.

check_calls_per_second: f64

Check rate above which a busy call site gets a frequency note.

report_calls_per_second: f64

Report rate above which a busy call site gets a batching note.

minimum_calls: u64

Calls a site must make before it gets a frequency note.

minimum_stage_wall: Duration

Sequential stages must run at least this long in total before their weights are compared with measured time.

weight_difference: f64

Smallest difference between a stage’s declared and measured share that produces weight advice.

negligible_stage_share: f64

A stage that took less than this share of the sequence’s time is too small to calibrate from one run (a flush that is trivial for this input may not be for the next). It keeps its declared weight, as long as the stages held this way together own at most half the bar.

uneven_pace_ratio: f64

A task whose slowest quarter of reported units took at least this many times as long as its fastest gets Kind::UnevenPace advice. It needs report timing, at least 8 reports, and minimum_stage_wall of wall time. A fastest quarter under the clock’s resolution counts as zero, so any slower quarter qualifies. Default 4.
