Also adjust E0322 error message to be more general, since it's used for DiscriminantKind and Pointee as well.

Also add rustc_deny_explicit_impl on the Tuple and Destruct marker traits.

Hey! It looks like you've submitted a new PR for the library teams!

If this PR contains changes to any rust-lang/rust public library APIs then please comment with @rustbot label +T-libs-api -T-libs to tag it appropriately. If this PR contains changes to any unstable APIs please edit the PR description to add a link to the relevant API Change Proposal or create one if you haven't already. If you're unsure where your change falls no worries, just leave it as is and the reviewer will take a look and make a decision to forward on if necessary.

Examples of T-libs-api changes:

  • Stabilizing library features
  • Introducing insta-stable changes such as new implementations of existing stable traits on existing stable types
  • Introducing new or changing existing unstable library APIs (excluding permanently unstable features / features without a tracking issue)
  • Changing public documentation in ways that create new stability guarantees
  • Changing observable runtime behavior of library APIs

cc @fee1-dead, it's not intended for Destruct to have user-defined impls, right?

yeah, I don't know if the trait system cares about it, but it is best to deny them

This is technically a breaking change. Should we do a crater run?

oh, it looks like this doesn't deny any trait on stable. nevermind.

Just below, the code swallows feature gate for rustc_specialization_trait when unboxed_closures is enabled. Could you remove that also?
