There was a problem hiding this comment.
Thanks, the modified explanation makes sense to me. Just a suggestion for adding a link to the actual RFC.

… r=jieyouxu Update E0517 message to reflect RFC 2195. E0517 occurs when a `#[repr(..)]` attribute is placed on an unsupported item. Currently, the explanation of the error implies that `#[repr(u*/i*)]` cannot be placed on fieldful enums, which is no longer the case since [RFC 2195](rust-lang/rfcs#2195) was [stabilized](rust-lang#60553), which allows placing `#[repr(u*/i*)]` and/or `#[repr(C)]` on fieldful enums to produce a defined layout. This PR doesn't (currently) add a description of the semantics of placing `#[repr(u*/i*)]` on a fieldful enum to the error explanation, it just removes the claims/implications that it is not allowed.
