* 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]>

| | | | | | 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.
