Snap for 8558685 from d9b77fd7cfd092afd5776b062fb2de36ba7c5218 to tm-frc-networking-release Change-Id: Ibfab39dc5035ed5cab154282a2d5acdd530a39d0
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.
