bors 99baddb57c Auto merge of #78068 - RalfJung:union-safe-assign, r=nikomatsakis ... consider assignments of union field of ManuallyDrop type safe Assigning to `Copy` union fields is safe because that assignment will never drop anything. However, with https://github.com/rust-lang/rust/pull/77547, unions may also have `ManuallyDrop` fields, and their assignments are currently still unsafe. That seems unnecessary though, as assigning `ManuallyDrop` does not drop anything either, and is thus safe even for union fields. I assume this will at least require FCP.		2020-12-15 11:31:03 +00:00
