diol is a benchmarking library for rust.
add the following to your Cargo.toml.
[dev-dependencies]
diol = "0.6.0"
[[bench]]
name = "my_benchmark"
harness = false
then in benches/my_benchmark.rs.
use diol::prelude::*;
fn main() -> std::io::Result<()> {
let mut bench = Bench::new(BenchConfig::from_args()?);
bench.register(slice_times_two, [4, 8, 16, 128, 1024]);
bench.run()?;
Ok(())
}
fn slice_times_two(bencher: Bencher, len: usize) {
let mut v = vec![0.0_f64; len];
bencher.bench(|| {
for x in &mut v {
*x *= 2.0;
}
black_box(&mut v);
});
}run the benchmark with cargo bench, or cargo bench --bench my_benchmark if you have multiple
benchmarks you can also pass in benchmark options using cargo bench --bench my_benchmark -- [OPTIONS...]
