Matthias Krüger bb45ea3acc Rollup merge of #146342 - folkertdev:c-variadic-errors-take-3, r=workingjubilee ... Improve C-variadic error messages: part 2 tracking issue: https://github.com/rust-lang/rust/issues/44930 a reimplementation of https://github.com/rust-lang/rust/pull/143546 that builds on https://github.com/rust-lang/rust/pull/146165. This PR - disallows coroutines (e.g. `async fn`) from having a `...` argument - disallows associated functions (both in traits and standard impl blocks) from having a `...` argument - splits up a generic "ill-formed C-variadic function" into specific errors about using an incorrect ABI, not specifying an ABI, or missing the unsafe keyword C-variadic coroutines probably don't make sense? C-variadic functions are for FFI purposes, combining that with async functions seems weird. For associated functions, we're just cutting scope. It's probably fine, but it's probably better to explicitly allow it. So for now, at least give a more targeted error message. Made to be reviewed commit-by-commit. cc `@workingjubilee` r? compiler		2025-09-10 20:29:10 +02:00
