Benchfmt.rs: Bringing Go's benchmarking and benchstat workflow to Rust

Bartek Płotka created benchfmt.rs, a Rust benchmarking tool that brings Go's benchstat workflow to Rust, featuring heap allocation tracking, pprof profiling support, and standardized benchmark output formatting. The tool includes a zero-dependency benchmark runner and converters for existing Rust frameworks like Criterion, enabling direct comparison of microbenchmarks between Go and Rust codebases. The author demonstrates the tool by benchmarking varint and Prometheus Remote Write 2.0 decoding implementations across both languages.
