easybench-wasm

This is a wasm32 browser friendly version of easybench

A lightweight benchmarking library which:

• uses linear regression to screen off sources of constant error;
• handles benchmarks which must mutate some state;
• has a very simple API!

use web_sys::console;
use easybench_wasm::{bench,bench_env};

// Simple benchmarks are performed with `bench`.
console::log_1(&format!("fib 200: {}", bench(|| fib(200) )).into());
console::log_1(&format!("fib 500: {}", bench(|| fib(500) )).into());

// If a function needs to mutate some state, use `bench_env`.
console::log_1(&format!("reverse: {}", bench_env(vec![1,2,3], |xs| xs.reverse())).into());
console::log_1(&format!("sort:    {}", bench_env(vec![1,2,3], |xs| xs.sort())).into());

Running the above yields the following:

fib 200:         38 ns   (R²=1.000, 26053498 iterations in 155 samples)
fib 500:        109 ns   (R²=1.000, 9131585 iterations in 144 samples)
reverse:          3 ns   (R²=0.998, 23684997 iterations in 154 samples)
sort:             3 ns   (R²=0.999, 23684997 iterations in 154 samples)
