|

```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.
