Snap for 10428683 from 166b9fb9b503067dfd08cdf95b98dd1987db3bf0 to mainline-adbd-release Change-Id: I95672896bbe625007d21e3df5c3fa1598472a5f8
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.
const
tables with static
tables.
