# Objective - Contributes to #16877 ## Solution - Expanded `bevy_platform_support::sync` module to provide API-compatible replacements for `std` items such as `RwLock`, `Mutex`, and `OnceLock`. - Removed `spin` from all crates except `bevy_platform_support`. ## Testing - CI --- ## Notes - The sync primitives, while verbose, entirely rely on `spin` for their implementation requiring no `unsafe` and not changing the status-quo on _how_ locks actually work within Bevy. This is just a refactoring to consolidate the "hacks" and workarounds required to get a consistent experience when either using `std::sync` or `spin`. - I have opted to rely on `std::sync` for `std` compatible locks, maintaining the status quo. However, now that we have these locks factored out into the own module, it would be trivial to investigate alternate locking backends, such as `parking_lot`. - API for these locking types is entirely based on `std`. I have implemented methods and types which aren't currently in use within Bevy (e.g., `LazyLock` and `Once`) for the sake of completeness. As the standard library is highly stable, I don't expect the Bevy and `std` implementations to drift apart much if at all. --------- Co-authored-by: BD103 <59022059+BD103@users.noreply.github.com> Co-authored-by: Benjamin Brienen <benjamin.brienen@outlook.com>
