# Objective Follow up to my previous MR #3718 to add new clippy warnings to bevy: - [x] [~~option_if_let_else~~](https://rust-lang.github.io/rust-clippy/master/#option_if_let_else) (reverted) - [x] [redundant_else](https://rust-lang.github.io/rust-clippy/master/#redundant_else) - [x] [match_same_arms](https://rust-lang.github.io/rust-clippy/master/#match_same_arms) - [x] [semicolon_if_nothing_returned](https://rust-lang.github.io/rust-clippy/master/#semicolon_if_nothing_returned) - [x] [explicit_iter_loop](https://rust-lang.github.io/rust-clippy/master/#explicit_iter_loop) - [x] [map_flatten](https://rust-lang.github.io/rust-clippy/master/#map_flatten) There is one commit per clippy warning, and the matching flags are added to the CI execution. To test the CI execution you may run `cargo run -p ci -- clippy` at the root. I choose the add the flags in the `ci` tool crate to avoid having them in every `lib.rs` but I guess it could become an issue with suprise warnings coming up after a commit/push Co-authored-by: Carter Anderson <mcanders1@gmail.com> |

bevy_ptr
The bevy_ptr crate provides low-level abstractions for working with pointers in a more safe way than using rust's raw pointers.
Rust has lifetimed and typed references (&'a T), unlifetimed and typed references (*const T), but no lifetimed but untyped references.
bevy_ptr adds them, called Ptr<'a>, PtrMut<'a> and OwningPtr<'a>.
These types are lifetime-checked so can never lead to problems like use-after-frees and must always point to valid data.
