|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 4246: Validate uses of self and super r=matklad a=djrenren This change follows on the validation of the `crate` keyword in paths. It verifies the following things: `super`: - May only be preceded by other `super` segments - If in a `UseItem` then all semantically preceding paths also consist only of `super` `self` - May only be the start of a path Just a note, a couple times while working on this I found myself really wanting a Visitor of some sort so that I could traverse descendants while skipping sub-trees that are unimportant. Iterators don't really work for this, so as you can see I reached for recursion. Considering paths are generally small a fancy debounced visitor probably isn't important but figured I'd say something in case we had something like this lying around and I wasn't using it.

See below** This pull requests implements simple validation of usages of the `crate` keyword in `Path`s. Specifically it validates that: - If a `PathSegment` is starts with the `crate` keyword, it is also the first segment of the `Path` - All other usages of `crate` in `Path`s are considered errors. This aligns with `rustc`'s rules. Unlike rustc this implementation does not issue a special error message in the case of `::crate` but it does catch the error. Furthermore, this change does not cover all error cases. Specifically the following is not caught: ```rust use foo::{crate} ``` This is because this check is context sensitive. From an AST perspective, `crate` is the root of the `Path`. Only by inspecting the full `UseItem` do we see that it is not in fact the root. This problem becomes worse because `UseTree`s are allowed to be arbitrarily nested: ```rust use {crate, {{crate, foo::{crate}}} ``` So this is a hard problem to solve without essentially a breadth-first search. In a traditional compiler, I'd say this error is most easily found during the AST -> HIR conversion pass but within rust-analyzer I'm not sure where it belongs. Under the implementation in this PR, such errors are ignored so we're *more correct* just not *entirely correct*. Co-authored-by: John Renner <[email protected]>

* Macro patterns are not confused with expressions.Aleksey Kladov2020-04-031-0/+3
| | | | | | | | | | | We treat macro calls as expressions (there's appropriate Into impl), which causes problem if there's expresison and non-expression macro in the same node (like in the match arm). We fix this problem by nesting macor patterns into another node (the same way we nest path into PathExpr or PathPat). Ideally, we probably should add a similar nesting for macro expressions, but that needs some careful thinking about macros in blocks: `{ am_i_expression!() }`.
