Criterion.rs v0.3 - Custom Measurements, Profiling Hooks, Custom Test Framework, API Changes

Posted on August 25, 2019 by bheisler.github.io

I’m pleased to announce the release of Criterion.rs v0.3, available today. Version 0.3 provides a number of new features including preliminary support for plugging in custom measurements (eg. hardware timers or POSIX CPU time), hooks to start/stop profilers, a new BenchmarkGroup struct that provides more flexibility than the older Benchmark and ParameterizedBenchmark structs, and an implementation of a #[criterion] custom-test-framework macro for those on Nightly. What is Criterion.rs? Criterion.rs is a statistics-driven benchmarking library for Rust.
