Add libunicode_xid build file. am: 062b4bd142 am: 98522dabfe am: 8b2bcf6811 am: 2b7efedaf7 Change-Id: I468444ab02e133ee2d3c6bfff0e831103d1d9500
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 = "0.0.4"
