Samir Talwar c7d9baaf66 Use references where possible instead of cloning. (#478) ... When trying to reduce the number of dependencies we use in the engine, I was blocked by a few `.clone()` calls that, on inspection, turned out to be completely unnecessary. I have replaced those with passing by reference, and then gone on a pedant spree. I enabled the `needless_pass_by_value` Clippy warning and fixed it everywhere that it highlighted. In most places, this meant adding `&`, but I also marked some types as `Copy`, which makes pass-by-value the right move. In one place, I replaced calls to `async_map` with `if` and `else`, to avoid constructing closures that capture across async boundaries. This means I could just delete `async_map`.
