Bug: b/162561729 Test: make and atest Merged-In: I4dd23de1154657dc6eea3ed72e9ba8b720a1e005 Change-Id: I7fe0b149b83117fddd949d28a024dfb981584ca8
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"
