2024 Edition

[Veykril]

Issue to track new edition things we need to implement

Quoting the edition guide:

• RPIT lifetime capture rules
• if let temporary scope: probably needs to be reflected in our mir?
• Tail expression temporary scope: same as above
• Match ergonomics: will likely only ship backwards compat diagnostics
• Unsafe extern blocks: Mostly done, diagnostic for missing unsafe in edition 2024 is missing though
• Unsafe attributes: Supported, but no diagnostics yet for missing unsafe wrapping for the given attributes
• unsafe_op_in_unsafe_fn warning
• Disallow references to static mut
• Never type fallback change: We always had this behavior I believe
• Macro Fragment Specifiers
• Missing macro fragment specifiers
• gen keyword
• Reserved syntax
• Add IntoIterator for Box<[T]>
• Unsafe functions
