# Objective Following #10756, we're now using raw pointers in BundleInserter and BundleSpawner. This is primarily to get around the need to split the borrow on the World, but it leaves a lot to be desired in terms of safety guarantees. There's no type level guarantee the code can't dereference a null pointer, and it's restoring them to borrows fairly liberally within the associated functions. ## Solution * Replace the pointers with `NonNull` and a new `bevy_ptr::ConstNonNull` that only allows conversion back to read-only borrows * Remove the closure to avoid potentially aliasing through the closure by restructuring the match expression. * Move all conversions back into borrows as far up as possible to ensure that the borrow checker is at least locally followed. |
