Feature gate for defaulted associated type_consts with associated_type_defaults *[View all comments](https://triagebot.infra.rust-lang.org/gh-comments/rust-lang/rust/pull/152385)* This PR for issue rust-lang/rust#130288 extends a feature gate that was already present for defaulted associated types to defaulted type consts under associated_type_defaults. Code added: ``` if ctxt == AssocCtxt::Trait && rhs.is_some() { gate!( &self, associated_type_defaults, i.span, "associated type defaults are unstable" ); } ``` Error produced: ``` error[E0658]: associated type defaults are unstable --> $DIR/type-const-associated-default.rs:4:5 | LL | type const N: usize = 10; | ^^^^^^^^^^^^^^^^^^^^^^^^^ | = note: see issue #29661 <https://github.com/rust-lang/rust/issues/29661> for more information = help: add `#![feature(associated_type_defaults)]` to the crate attributes to enable = note: this compiler was built on YYYY-MM-DD; consider upgrading it if it is out of date warning: the feature `min_generic_const_args` is incomplete and may not be safe to use and/or cause compiler crashes --> $DIR/type-const-associated-default.rs:1:12 | LL | #![feature(min_generic_const_args)] | ^^^^^^^^^^^^^^^^^^^^^^ | = note: see issue #132980 <https://github.com/rust-lang/rust/issues/132980> for more information = note: `#[warn(incomplete_features)]` on by default error: aborting due to 1 previous error; 1 warning emitted For more information about this error, try `rustc --explain E0658`. ``` Thanks to @BoxyUwU for the guidance on this issue.
