use-js-identifier

ASCII-safe JavaScript identifier primitives for RustUse.

Experimental

use-js-identifier is experimental while use-js remains below 0.3.0.

Example

use use_js_identifier::{JsIdentifier, is_valid_ascii_js_identifier};

let identifier = JsIdentifier::new("createApp")?;

assert_eq!(identifier.as_str(), "createApp");
assert!(is_valid_ascii_js_identifier("$value_1"));
# Ok::<(), use_js_identifier::JsIdentifierError>(())

Scope

• Ordinary ASCII-safe JavaScript identifier validation.
• $, _, ASCII letters, and ASCII digits in continuation positions.
• Small newtype helpers for metadata models.

Non-goals

• Complete Unicode ECMAScript identifier validation.
• Keyword or reserved-word checks.
• Source-code parsing.

Unicode-complete ECMAScript identifier validation is future work.
