Divan is a fast and simple benchmarking library for Rust projects, used via a #[divan::bench] attribute and cargo bench. It offers allocation profiling, generic parameter benchmarking, thread contention insights, and statistical output.

Use cases

• benchmark rust functions
• measure memory allocations in rust code
• compare performance of generic rust functions
• run benchmarks in CI
• find an alternative to criterion.rs
• profile thread contention in rust

When to choose

• you want a simpler, faster benchmarking API than Criterion
• you need allocation and throughput metrics out of the box
• you benchmark generic functions with multiple parameter cases
• you want quick benchmark runs suitable for CI

When to avoid

• you need Criterion's mature statistical analysis and HTML reports
• you are not working in Rust
• you need flamegraph-style CPU profiling rather than benchmarking
