Continue parsing after parent type args and suggest using angle brackets ``` error[E0214]: parenthesized parameters may only be used with a trait --> $DIR/E0214.rs:2:15 | LL | let v: Vec(&str) = vec!["foo"]; | ^^^^^^ | | | only traits may use parentheses | help: use angle brackets instead: `<&str>` ``` r? @zackmdavis

2019-01-20Recover from parse errors in struct literal fieldsEsteban Küber-7/+30
Attempt to recover from parse errors while parsing a struct's literal fields by skipping tokens until a comma or the closing brace is found. This allows errors in other fields to be reported.

2019-01-16Auto merge of #57321 - petrochenkov:atokens, r=nikomatsakisbors-3/+11
Implement basic input validation for built-in attributes Correct top-level shape (`#[attr]` vs `#[attr(...)]` vs `#[attr = ...]`) is enforced for built-in attributes, built-in attributes must also fit into the "meta-item" syntax (aka the "classic attribute syntax"). For some subset of attributes (found by crater run), errors are lowered to deprecation warnings. NOTE: This PR previously included https://github.com/rust-lang/rust/pull/57367 as well.

Delay gensym creation for "underscore items" (`use foo as _`/`const _`) until name resolution So they cannot be cloned by macros. See https://github.com/rust-lang/rust/pull/56303 for the discussion. Mostly fix cross-crate use of underscore items by inverting the "gensyms are lost in metadata" bug as described in https://github.com/rust-lang/rust/pull/56303#issuecomment-442464695. Fix unused import warnings for single-segment imports (first commit) and `use crate_name as _` imports (as specified in https://github.com/rust-lang/rust/pull/56303#issuecomment-442274118). Prohibit accidentally implemented `static _: TYPE = EXPR;` (cc https://github.com/rust-lang/rust/pull/55983). Add more tests for `use foo as _` imports.

Before parsing argument names and types, try to consume an incorrectly included doc comment or attribute in order to recover and continue parsing the rest of the fn definition.
