Mathspy 469b218f20 Improve ergonomics of platform_support's Instant (#17577) ... # Objective - Make working with `bevy_time` more ergonomic in `no_std` environments. Currently `bevy_time` expects the getter in environments where time can't be obtained automatically via the instruction set or the standard library to be of type `*mut fn() -> Duration`. [`fn()`](https://doc.rust-lang.org/beta/std/primitive.fn.html) is already a function pointer, so `*mut fn()` is a _pointer to a function pointer_. This is harder to use and error prone since creating a pointer out of something like `&mut fn() -> Duration` when the lifetime of the reference isn't static will lead to an undefined behavior once the reference is freed ## Solution - Accept a `fn() -> Duration` instead ## Testing - I made a whole game on the Playdate that relies on `bevy_time` heavily, see: [bevydate_time](1b4f02adcd/src/lib.rs (L510-L546)) for usage of the Instant's getter. --- ## Showcase <details> <summary>Click to view showcase</summary> https://github.com/user-attachments/assets/f687847f-6b62-4322-95f3-c908ada3db30 </details> ## Migration Guide This is a breaking change but it's not for people coming from Bevy v0.15 ### Small thank you note Thanks to my friend https://github.com/repnop for helping me understand how to deal with function pointers in `unsafe` environments Co-authored-by: Wesley Norris <repnop@repnop.dev>		2025-02-02 15:50:48 +00:00
