* Introduce dedicated AST node for unionAleksey Kladov2019-11-253-12/+22
| | | | | | | | | | Although structs and unions have the same syntax and differ only in the keyword, re-using the single syntax node for both of them leads to confusion in practice, and propagates further down the hir in an upleasent way. Moreover, static and consts also share syntax, but we use different nodes for them.

* Fix parsing of "postfix" range expressions.Geoffry Song2019-11-151-30/+24
| | | | | | | | | | Right now they are handled in `postfix_dot_expr`, but that doesn't allow it to correctly handle precedence. Integrate it more tightly with the Pratt parser instead. Also includes a drive-by fix for parsing `match .. {}`. Fixes #2242.

|\ | | | | | | | | | | | | | | | | | | | | | | | | 1951: Lower the precedence of the `as` operator. r=matklad a=goffrie Previously, the `as` operator was being parsed like a postfix expression, and therefore being given the highest possible precedence. That caused it to bind more tightly than prefix operators, which it should not. Instead, parse it somewhat like a normal binary expression with some special-casing. Fixes #1851.

* | Fix parsing of block expressions in "forbid_structs" contexts.Geoffry Song2019-10-032-10/+25
|/ | | | | | Forbidding block expressions entirely is too strict; instead, we should only forbid them in contexts where we are parsing an optional RHS (i.e. the RHS of a range expression).

|\ | | | | | | | | | | | | | | | | | | | | | | 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]>

* don't break parser error recovery in presence of macrosAleksey Kladov2019-09-121-2/+2
| | | | | | | Parser has the invariant that `{}` are balanced. Previous code tried (unsucesfuly) maintain the same invariant for `$()` as well, but it was done in a rather ad-hoc manner: it's not at all obvious that it is possible to maintain both invariants!

* Handle `Struct { box i }` syntaxDylan MacKenzie2019-08-241-0/+3
| | | | | | Named structs can have `box` patterns that will bind to their fields. This is similar to the behavior of the `ref` and `mut` fields, but is at least a little bit surprising.
