Jacob Pratt 05f22c3614 Rollup merge of #121840 - oli-obk:freeze, r=dtolnay ... Expose the Freeze trait again (unstably) and forbid implementing it manually non-emoji version of https://github.com/rust-lang/rust/pull/121501 cc #60715 This trait is useful for generic constants (associated consts of generic traits). See the test (`tests/ui/associated-consts/freeze.rs`) added in this PR for a usage example. The builtin `Freeze` trait is the only way to do it, users cannot work around this issue. It's also a useful trait for building some very specific abstrations, as shown by the usage by the `zerocopy` crate: https://github.com/google/zerocopy/issues/941 cc ```@RalfJung``` T-lang signed off on reexposing this unstably: https://github.com/rust-lang/rust/pull/121501#issuecomment-1969827742		2024-03-11 03:47:19 -04:00
