Matthias Krüger 334d7bd698 Rollup merge of #137323 - joshlf:transmute-npo, r=RalfJung ... Guarantee behavior of transmuting `Option::<T>::None` subject to NPO In https://github.com/rust-lang/rust/pull/115333, we added a guarantee that transmuting from `[0u8; N]` to `Option<P>` is sound where `P` is a pointer type subject to the null pointer optimization (NPO). It would be useful to be able to guarantee the inverse - that a `None::<P>` value can be transmutes to an array and that will yield `[0u8; N]`. Closes #117591		2025-05-24 16:08:45 +02:00
