Snap for 6912731 from 7ee0d916263e10a1678d028fc4ba4c6cfdb77bb1 to emu-30-release Change-Id: I5d6fad5cc72b3f84ba272a34c2f6ee69b2d65137
Determine if a char is a valid identifier for a parser and/or lexer according to Unicode Standard Annex #31 rules.
extern crate unicode_xid; use unicode_xid::UnicodeXID; fn main() { let ch = 'a'; println!("Is {} a valid start of an identifier? {}", ch, UnicodeXID::is_xid_start(ch)); }
unicode-xid supports a no_std feature. This eliminates dependence on std, and instead uses equivalent functions from core.
