# unicode-xid
Determine if a `char` is a valid identifier for a parser and/or lexer according to
[Unicode Standard Annex #31](http://www.unicode.org/reports/tr31/) rules.
[](https://travis-ci.org/unicode-rs/unicode-xid)
[Documentation](https://unicode-rs.github.io/unicode-xid/unicode_xid/index.html)
```rust
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));
}
```
# features
unicode-xid supports a `no_std` feature. This eliminates dependence
on std, and instead uses equivalent functions from core.
# crates.io
You can use this package in your project by adding the following
to your `Cargo.toml`:
