Snap for 6741352 from e6512220fea4425c82e21a3807214414b59e8fd8 to rvc-d2-release Change-Id: I14f46b3b2174abaaa21bb5932dbc51d4b7746cce
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"
