Keith-Cancel 73a991fb9d Allow provisional mgca syntax of type const <IDENT> = <EXPR> to be reconized.
Revert, but without type const.

Update symbol for feature err, then update suggestion output, and lastly update tests that change because of those.

Update these new tests with the correct syntax, and few existing tests with the new outputs the merge with main added.

Fix for tidyfmt and some errors when manually resolving a merge conflicts.

Update these tests to use update error messages and type const syntax.

Update comments and error message to use new syntax instead of old type_const attribute.

Remove the type_const attribute

update some more tests to use the new syntax.

Update these test cases.

update feature gate test

Change gate logic for `mgca_type_const_syntax` to work also if `min_generic_const_args` is enabled.

Create a new feature gate that checks for the feature before expansion.

Make rustfmt handle the `type const` syntax correctly.

Add a convience method to check if a RhsKind is type const.

Rename `Const` discriminant to `Body` for `ConstItemRhsKind`

Give the `TraitItemKind` flag an enum instead of a simple bool to better describe what the flag is for.

Update formatting for these match statements.

Update clippy test to use type const syntax.

Update test to use type const syntax.

update rustfmt to match ast items.

Update clippy to match ast and hir items.

Few more test cases that used old attribute, instead of 'type const'

Update to match the output from the feature gate checks.

tidyfmt adjustments.

Update the is_type_const, so I can constrain record!(..) in encoder.rs

Update conditional compilation test.

Move the feature gate to after expansion to allow for cfg(...) to work.

Update some more tests to use the new syntax.

Update type const tests in associated-const-bindings to use new syntax.

Don't check based off the attribute, but the item here.

Update some tests outside of the const_generics folder that were using #[type_const]

update the tests in associated consts that use #[type_const] to use type const

Update these mgca tests with the type const syntax.

Add a flag to TraitItemKind for detecting type const for now. Maybe later change ItemConstRhs to have optional consts but that touches a lot more lines of code.

Don't need into for these now that it's a query.

Add is_type_const query to handle foreign def ids.

update this test to use type const syntax.

Fix logic here, we only want to lower if there is expression in this case.

Update built-in macros to use ConstItemRhsKind

Update more instance of the old ConstItemRhs.

Rename ConstItemKind to ConstItemRhsKind, I noticed there is a typed called ConstantItemKind, so add the Rhs to the name to avoid confusion.

Update lower to use ConstItemKind

Add an other helper method to check if the rhs kinda has an expr.

Update item parse to use ConstItemKind enum.

Felt the field name could a be little clear when editing a few other things.

Change the ConstItem struct see know if we have a type const or regular const.

Make sure this syntax is properly feature gated.

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.

Why Rust?

  • Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.

  • Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.

  • Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
