* Allow attributes on top level expressionpcpthm2019-03-194-0/+152
| | | | | | A top level expression is either - a expression statement or - the last expression in a block

|\ | | | | | | | | | | | | | | | | | | | | | | 991: Use Marker argument for item parsers r=matklad a=pcpthm Before doing this for expressions, I found that the pattern (Marker argument) should be applied to the item parsers because visiblity and modifiers are parsed in a separate function. Fixed some parser bugs: - Fix pub_expr: `pub 42;` was allowed. - Fix incorrect parsing of crate::path: incorrectly parsed as `crate` as a visibility. Co-authored-by: pcpthm <[email protected]>

|\ \ | | | | | | | | | | | | | | | | | | | | | | | | | | | 983: support remainder assignment operator r=matklad a=JeanMertz `%=` was returning errors for me, turns out it wasn't added as a valid assignment operation. I'm not sure what the best location would be to add a test for this. Please let me know and I'll add one. Co-authored-by: Jean Mertz <[email protected]>

* Enable parsing of attributes inside a match blockVille Penttinen2019-02-178-0/+493
| | | | | | | We allow invalid inner attributes to be parsed, e.g. inner attributes that are not directly after the opening brace of the match block. Instead we run validation on `MatchArmList` to allow better reporting of errors.
