Snap for 8564071 from bd8e405fbb6cfa58acb6dfcaaa72ca7e1f44b594 to mainline-art-release Change-Id: Icf39f66f359966e01b2914e7c737c0d98c0cff18
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.
