| * Add test for `<T>::Item`Florian Diebold2019-09-171-10/+22
| |
| * Refactor some moreFlorian Diebold2019-09-174-57/+100
| | | | | | | | | | | | Type-relative paths (`<T>::foo`) also need to work in type context, for example `<T>::Item` is legal. So rather than returning the type ref from the resolver function, just check it before.
| * Refactor associated item resolution moreFlorian Diebold2019-09-172-124/+120
| | | | | | | | | | When resolving an associated item in value namespace, use the `Ty` lowering code for the segments before the last instead of replicating it.
| * Refactor a bit to prepare for resolving trait assoc itemsFlorian Diebold2019-09-1710-52/+83
| |
| * Resolve assoc types on type parametersFlorian Diebold2019-09-172-24/+61
| | | | | | | | | | | | E.g. `fn foo<T: Iterator>() -> T::Item`. It seems that rustc does this only for type parameters and only based on their bounds, so we also only consider traits from bounds.

| * | remove confusing codeAleksey Kladov2019-09-171-31/+1
| | | | | | | | | | | | | | | | | | I must confess I don't really understand what this code is trying to do, but it definitely misreports changes during fixedpoint iteration, and no tests fail if I remove it, so...

|\ | | | | | | | | | | | | | | | | | | | | | | 1848: Parse `..` as a full pattern r=matklad a=ecstatic-morse Resolves #1479. This PR implements [RFC 2707](https://github.com/rust-lang/rfcs/pull/2707) in the parser. It introduces a new `DotDotPat` AST node modeled on `PlaceholderPat` and changes the parsing of tuple and slice patterns to conform to the RFC. Notably, this PR does *not* change the resulting AST when `..` appears in a struct pattern (e.g. `Struct { a, b: c, .. }`). I *think* this is the behavior mandated by RFC 2707, but someone should confirm this. Co-authored-by: Dylan MacKenzie <[email protected]>
