[tguichaoua]

unsafe_op_in_unsafe_fn will be warn by default in rust edition 2024 (https://github.com/rust-lang/rust/pull/112038).

What solution would you like?

Enable unsafe_op_in_unsafe_fn.

Additional context

I have opened a PR (#11591) that enables the lint at workspace level and fixes the lint in some crates. Nevertheless, the clippy::undocumented-unsafe-blocks lint makes unsafe blocks require a safety comment to describe them. The following crates require someone with enough knowledge about them to provide proper safety comments.

• [x] bevy_dynamic_plugin #11622
• [ ] bevy_ecs
• [x] bevy_ptr #11610
