* Merge #1848bors[bot]2019-09-152-10/+43
|\ | | | | | | | | | | | | | | | | | | | | | | 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.

The [RFC-2565](https://github.com/rust-lang/rfcs/blob/master/text/2565-formal-function-parameter-attributes.md) specifies `#[attributes]` to function parameters: ```rust fn foo(#[attr] a, #[unused] b, #[must_use] ...) { // ... } ``` This PR adds those attributes into grammar and to the parser, extending corresponding inline tests.

* Remove parse error on array initializer attributesRyan Cumming2019-06-301-11/+0
| | | | | This is actually allowed by the `rustc` parser but most attributes will fail later due to attributes on expressions being experimental.
* Support attributes on array membersRyan Cumming2019-06-301-0/+28
| | | | | | | | | | | | Array members are allow to have attributes such as `#[cfg]`. This is a bit tricky as we don't know if the first expression is an initializer or a member until we encounter a `;`. This reuses a trick from `stmt` where we remember if we saw an attribute and then raise an error if the first expression ends up being an initializer. This isn't perfect as the error isn't correctly located on the attribute or initializer; it ends up immediately after the `;`.
