      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(())
      }
      

      From the CI
