Implemented a compiler diagnostic for move async mistake Fixes #79694 First time contributing, so I hope I'm doing everything right. (If not, please correct me!) This code performs a check when a move capture clause is parsed. The check is to detect if the user has reversed the async move keywords and to provide a diagnostic with a suggestion to fix it. Checked code: ```rust fn main() { move async { }; } ``` Previous output: ```txt PS C:\Repos\move_async_test> cargo build Compiling move_async_test v0.1.0 (C:\Repos\move_async_test) error: expected one of `|` or `||`, found keyword `async` --> src\main.rs:2:10 | 2 | move async { }; | ^^^^^ expected one of `|` or `||` error: aborting due to previous error error: could not compile `move_async_test` ``` New output: ```txt PS C:\Repos\move_async_test> cargo +dev build Compiling move_async_test v0.1.0 (C:\Repos\move_async_test) error: the order of `move` and `async` is incorrect --> src\main.rs:2:13 | 2 | let _ = move async { }; | ^^^^^^^^^^ | help: try switching the order | 2 | let _ = async move { }; | ^^^^^^^^^^ error: aborting due to previous error error: could not compile `move_async_test` ``` Is there a file/module where these kind of things are tested? Would love some feedback 😄 |
