repr(transparent): it's fine if the one non-1-ZST field is a ZST This code currently gets rejected: ```rust #[repr(transparent)] struct MyType([u16; 0]) ``` That clearly seems like a bug to me: `repr(transparent)` [got defined ](https://github.com/rust-lang/rust/issues/77841#issuecomment-716575747) as having any number of 1-ZST fields plus optionally one more field; `MyType` clearly satisfies that definition. This PR changes the `repr(transparent)` logic to actually match that definition. |
