# Objective - Contributes to #16877 ## Solution - Initial creation of `bevy_platform_support` crate. - Moved `bevy_utils::Instant` into new `bevy_platform_support` crate. - Moved `portable-atomic`, `portable-atomic-util`, and `critical-section` into new `bevy_platform_support` crate. ## Testing - CI --- ## Showcase Instead of needing code like this to import an `Arc`: ```rust #[cfg(feature = "portable-atomic")] use portable_atomic_util::Arc; #[cfg(not(feature = "portable-atomic"))] use alloc::sync::Arc; ``` We can now use: ```rust use bevy_platform_support::sync::Arc; ``` This applies to many other types, but the goal is overall the same: allowing crates to use `std`-like types without the boilerplate of conditional compilation and platform-dependencies. ## Migration Guide - Replace imports of `bevy_utils::Instant` with `bevy_platform_support::time::Instant` - Replace imports of `bevy::utils::Instant` with `bevy::platform_support::time::Instant` ## Notes - `bevy_platform_support` hasn't been reserved on `crates.io` - ~~`bevy_platform_support` is not re-exported from `bevy` at this time. It may be worthwhile exporting this crate, but I am unsure of a reasonable name to export it under (`platform_support` may be a bit wordy for user-facing).~~ - I've included an implementation of `Instant` which is suitable for `no_std` platforms that are not Wasm for the sake of eliminating feature gates around its use. It may be a controversial inclusion, so I'm happy to remove it if required. - There are many other items (`spin`, `bevy_utils::Sync(Unsafe)Cell`, etc.) which should be added to this crate. I have kept the initial scope small to demonstrate utility without making this too unwieldy. --------- Co-authored-by: TimJentzsch <TimJentzsch@users.noreply.github.com> Co-authored-by: Chris Russell <8494645+chescock@users.noreply.github.com> Co-authored-by: François Mockers <francois.mockers@vleue.com>
