Add explicit default 2015. am: 1809e3e889 am: 2e20f6a622 am: 18ee23b52a Change-Id: I09e1005a62e8a8076dd99b1ad8d960f47bcd47dd
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.
You can use this package in your project by adding the following to your Cargo.toml:
[dependencies] unicode-xid = "0.1.0"
