What's Changed

Manual sampling for criterion

Note: ignored under CodSpeed simulation mode (single measured iteration). Only takes effect in walltime mode.

We introduced a new finer control way of defining a criterion benchmark to have full control over how many times your code is ran.
This bypasses criterion's original sampler, which we still recommend using if you do not have specific control needs.

use codspeed_criterion_compat::{criterion_group, criterion_main, Criterion, IterManualOptions};

fn bench_my_function(c: &mut Criterion) {
    c.bench_function("my_function", |b| {
        b.iter_manual_unstable(
            IterManualOptions::new()
                .rounds(5)   // 5 measurement samples, can be lower than criterion's imposed 10
                .iters(1000)  // 1000 calls per sample
                .warmup(5),   // 5 unmeasured warmup iterations
            || my_function(),
        );
    });
}

criterion_group!(benches, bench_my_function);
criterion_main!(benches);

Please note that this API is still under development and may change with future releases.
