More concretely, given code like this:\n\n```rust\nuse tracing::*;\nuse tracing_timing::{Builder, Histogram};\nlet subscriber = Builder::default().build(|| Histogram::new_with_max(1_000_000, 2).unwrap());\nlet dispatcher = Dispatch::new(subscriber);\ndispatcher::with_default(\u0026dispatcher, || {\n trace_span!(\"request\").in_scope(|| {\n // do a little bit of work\n trace!(\"fast\");\n // do a lot of work\n trace!(\"slow\");\n })\n});\n```\n\nYou can produce something like this (see `examples/pretty.rs`):\n\n```text\nfast:\nmean: 173.2µs, p50: 172µs, p90: 262µs, p99: 327µs, p999: 450µs, max: 778µs\n 25µs | * | 2.2th %-ile\n 50µs | * | 2.2th %-ile\n 75µs | * | 4.7th %-ile\n 100µs | *** | 11.5th %-ile\n 125µs | ***** | 24.0th %-ile\n 150µs | ******* | 41.1th %-ile\n 175µs | ******** | 59.2th %-ile\n 200µs | ******* | 75.4th %-ile\n 225µs | ** | 80.1th %-ile\n 250µs | *** | 87.3th %-ile\n 275µs | *** | 94.4th %-ile\n 300µs | ** | 97.8th %-ile\n\nslow:\nmean: 623.3µs, p50: 630µs, p90: 696µs, p99: 770µs, p999: 851µs, max: 950µs\n 500µs | * | 1.6th %-ile\n 525µs | ** | 4.8th %-ile\n 550µs | *** | 10.9th %-ile\n 575µs | ***** | 22.2th %-ile\n 600µs | ******* | 37.9th %-ile\n 625µs | ******** | 55.9th %-ile\n 650µs | ******* | 72.9th %-ile\n 675µs | ****** | 85.6th %-ile\n 700µs | **** | 93.5th %-ile\n 725µs | ** | 97.1th %-ile\n```\n\nWhen [`TimingSubscriber`] is used as the `tracing::Dispatch`, the time between each event in a\nspan is measured using [`quanta`], and is recorded in \"[high dynamic range histograms]\" using\n[`hdrhistogram`]'s multi-threaded recording facilities. The recorded timing information is\ngrouped using the [`SpanGroup`] and [`EventGroup`] traits, allowing you to combine recorded\nstatistics across spans and events.\n\n [`tracing`]: https://docs.rs/tracing-core/\n [high dynamic range histograms]: https://hdrhistogram.github.io/HdrHistogram/\n [`hdrhistogram`]: https://docs.rs/hdrhistogram/\n [`quanta`]: https://docs.rs/quanta/\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjonhoo%2Ftracing-timing","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjonhoo%2Ftracing-timing","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjonhoo%2Ftracing-timing/lists"}
