Snap for 6739696 from 18f8214edc66b7f9babaaba72422de25eda4b4d4 to rvc-d1-b-release Change-Id: Idb5d03907c42ac45a1a3acf0624ff384b6b2eab6
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"
