Snap for 8191477 from 869fec56d6999075fe2c0417491cbe8851e78a19 to tm-frc-networking-release Change-Id: I90331b7ecffeb283775119a6a9a73cdacac7279b
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.
