Criterion.rs

As explained in Latency

Criterion is a Rust benchmarking library for statistically evaluating the performance of code.

How Latency covers it

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 it assumes

Assumes basic Rust and algorithm familiarity while demonstrating the benchmark setup and measurement workflow directly.

What you can do after

Diagnose performance with statistically informed timings, compare implementations, and locate costly call paths using flame graphs.

How it connects

Connects benchmarking with microbenchmarks, runtime analysis, algorithmic complexity, CPU profiling, flame graphs, and optimization.
