Add `future_prelude_collision` lint Implements #84594. (RFC rust-lang/rfcs#3114 ([rendered](https://github.com/rust-lang/rfcs/blob/master/text/3114-prelude-2021.md))) Not entirely complete but wanted to have my progress decently available while I finish off the last little bits. Things left to implement: * [x] UI tests for lints * [x] Only emit lint for 2015 and 2018 editions * [ ] Lint name/message bikeshedding * [x] Implement for `FromIterator` (from best I can tell, the current approach as mentioned from [this comment](https://github.com/rust-lang/rust/issues/84594#issuecomment-847288288) won't work due to `FromIterator` instances not using dot-call syntax, but if I'm correct about this then that would also need to be fixed for `TryFrom`/`TryInto`)* * [x] Add to `rust-2021-migration` group? (See #85512) (added to `rust-2021-compatibility` group) * [ ] Link to edition guide in lint docs *edit: looked into it, `lookup_method` will also not be hit for `TryFrom`/`TryInto` for non-dotcall syntax. If anyone who is more familiar with typecheck knows the equivalent for looking up associated functions, feel free to chime in. |
