Criterion.rs
Criterion.rs is a Rust benchmarking library for statistically driven measurement and evaluation of code performance.
Refactoring to Rust
Criterion is a Rust benchmarking library that performs statistically driven performance measurements.
- How it is used
- Measures Rust code and Rust-integrated Python code when performance comparisons need more reliable results.
- How deep it goes
- Explains configuration, benchmark registration, iteration, optimization control, and sample output, but not the underlying statistical methodology.
- Examples
- Uses integer-width microbenchmarks and a pure-Python versus Rust-extension JSON calculation.
- What you can do after
- Apply it via Cargo to build benchmark targets, measure functions, and compare reported timing ranges.
Latency
Criterion is a Rust benchmarking library for statistically evaluating the performance of code.
- How it is used
- Measures Rust code reliably while guiding performance work from runtime evidence toward targeted optimization.
- How deep it goes
- Provides setup, execution, statistical output, implementation comparison, and profiling, but does not detail Criterion internals.
- Examples
- Uses recursive, memoized, and iterative Fibonacci implementations, cargo bench output, outlier reports, and a flame graph.
- What you can do after
- Diagnose performance with statistically informed timings, compare implementations, and locate costly call paths using flame graphs.
Idiomatic Rust
Criterion.rs is a Rust benchmarking library that provides statistically oriented and feature-rich performance measurement.
- How it is used
- Provides feature-rich performance measurement for running benchmarks on stable Rust.
- How deep it goes
- Identifies a feature-rich benchmarking tool and Haskell port, but does not detail its API or statistical methods.
- What you can do after
- Apply it to run benchmarks on stable Rust.
