As provided for by rust-lang/rfcs#2071, this is a tracking issue for impl Trait in:

  • const items
  • static items
  • let bindings

Steps:

Unresolved questions:

  • Should the part about let bindings be recast more generally to be about coercions? This would allow foo as impl Debug and foo: impl Debug as well.

Blocking issues:

Incomplete. Search the F-impl_trait_in_bindings issue.

What's the status on this now? Is it ready to be stabilised?

The implementation was removed as part of #86729 and the corresponding checkbox should be unchecked.

Hopefully there will be soon, as it was the cleanest way for me to solve an issue just now.
