I'm benchmarking a concurrent data structure where individual operations are in the 100-200ns range. I need to measure latency distributions (p99, p99.9) rather than just throughput. I'm familiar with divan and criterion, but from what I understand by going through their docs and source code, they don't provide an API to test tail-latency, they focus on agregate throughput/mean.

Any crate recommendations or repos with a good tail-latency benchmarking methodology I can use as a reference?
