Snap for 5910202 from 1aa4cc3756db5ea4ff01b5800a5197f75249276a to rvc-release Change-Id: I75b728633d3110df7bbfae8f1f6f2585665519d8
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"
