Detailed Description

Rerpresentation of Option<String>. Rust has a Option<non-null ptr> optimization that None is NULL on the byte level. Thus, it's not a tagged enum. To check whether it's a Some(String) or None use helpers:

• LIB_RUBY_PARSER_maybe_string_is_some
• LIB_RUBY_PARSER_maybe_string_is_none
