Reject overly generic assoc const binding types Split off from #119385 to make #119385 easier to review. --- In the *instantiated* type of assoc const bindings 1. reject **early-bound generic params** * Provide a rich error message instead of ICE'ing ([#108271](https://github.com/rust-lang/rust/issues/108271)). * This is a temporary and semi-artificial restriction until the arrival of *generic const generics*. * It's quite possible that rustc could already perfectly support this subset of generic const generics if we just removed some checks (some `.no_bound_vars().expect(…)`) but even if that was the case, I'd rather gate it behind a new feature flag. Reporting an error instead of ICE'ing is a good first step towards an eventual feature gate error. 2. reject **escaping late-bound generic params** * They lead to ICEs before & I'm pretty sure that they remain incorrect even in a world with *generic const generics* --- Together with #118668 & #119385, this supersedes #118360. Fixes #108271. |
