## Compatibility Notes

- [Many unsafe precondition checks now run for user code with debug

This change helps users catch undefined behavior in their code, though
the details of how much is checked are generally not stable.

Trait`](https://togithub.com/rust-lang/rust/pull/121679)

type](https://togithub.com/rust-lang/rust/pull/118882)
