## Special Unicode Productions
|

|

The following productions in the Rust grammar are defined in terms of Unicode properties:
|
||||
`ident`, `non_null`, `non_star`, `non_eol`, `non_slash`, `non_single_quote` and `non_double_quote`.
|
||||
`ident`, `non_null`, `non_star`, `non_eol`, `non_slash_or_star`, `non_single_quote` and `non_double_quote`.
