44 ### Using the tracing crate
46 You can use the ATrace layer for the [tracing](https://docs.rs/tracing/latest/tracing/) crate.
51 Add the tracing libraries to your `rustlibs` in `Android.bp`:

21 There is a benchmark for the tracing crate subscriber - `libatrace_tracing_subscriber_benchmark`.
24 Similarly to the wrapper benchmarks, the subscriber is measured with tracing off and on. There are
