I’m still working on a benchmark for my wordle solver. The thing itself works, but I want it to print statuses while benching.
I cannot do it. I’ve spent hours on this, even tried to make the bench async and run it in a separate Tokio task. I cannot share my bench strict over a thread, and cloning is impossible too, because of something.
Sometimes, the lifetime and ownership stuff of rust really gets annoying. C would’ve just done the stuff and be done with it. (Maybe)
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(())
}

I you share your code here, maybe someone can help.
The whole code is here
(It does not compile right now)
