Certainly!

I still need to think about what I want in terms of licensing (it’s currently MPL 2.0), but once I figure that out, I’d love some help. Also, naming things is hard. 🙃

I have seen something similar on Twitter a while ago. That one shut down, so i decided to build my own.

The whole code is here

(It does not compile right now)

I understand why it does not work, but I don’t know how to achieve what I’m looking for.

This is the code snippet from the binary:

    let wl = BuiltinWList::default();
    let builder: GameBuilder<'_, BuiltinWList> = game::Game::builder(&wl)
        .length(cli.length)
        .max_steps(cli.max_steps)
        .precompute(cli.precompute);
    let solver: AnyBuiltinSolver<'_, BuiltinWList> = cli.solver.to_solver(&wl);
    let bench = BuiltinBenchmark::build(&wl, solver, builder, cli.threads)?;
    trace!("{bench:#?}");

    bench.start()?;

    loop {
        sleep_ms(1000);
        println!("{}", bench.report());
        if bench.is_finished() {
            break;
        }
    }

    Ok(())
}

Thanks! Actually, I decided to make this library during a OS course in which I made a microkernel (non usable but you can found it here). So currently the project is only to make this library, and I hope other projects will begin to use it if it becomes enough stable ^^
