Snap for 7550844 from 788b1177692dad380cf13694e7bf948d3f451423 to mainline-os-statsd-release Change-Id: If0993ccf959b94c05448ecf5656d34ecdfe7b39c
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.
