Snap for 7149879 from 985c813f8f642419249c0a5b1f6a40b12c5e1074 to sc-v2-release Change-Id: I2bc6cb23443b9fbc11a5d49312e52f62467b9b23
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.
