![]() # Objective Improve the code quality of the multithreaded executor. ## Solution * Remove some unused variables. * Use `Mutex::get_mut` where applicable instead of locking. * Use a `startup_systems` FixedBitset to pre-compute the starting systems instead of building it bit-by-bit on startup. * Instead of using `FixedBitset::clear` and `FixedBitset::union_with`, use `FixedBitset::clone_from` instead, which does only a single copy and will not allocate if the target bitset has a large enough allocation. * Replace the `Mutex` around `Conditions` with `SyncUnsafeCell`, and add a `Context::try_lock` that forces it to be synchronized fetched alongside the executor lock. This might produce minimal performance gains, but the focus here is on the code quality improvements. |
