Crate use_python_identifier 

use-python-identifier

ASCII-safe Python identifier primitives for RustUse.

Experimental

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

Example

use use_python_identifier::{PythonIdentifier, is_valid_ascii_python_identifier};

let identifier = PythonIdentifier::new("async_task")?;

assert_eq!(identifier.as_str(), "async_task");
assert!(is_valid_ascii_python_identifier("_value_1"));

Scope

• Ordinary ASCII-safe Python identifier validation.
• Hard Python keyword rejection through use-python-keyword.
• Dunder-name and private-name metadata helpers.

Non-goals

• Complete Unicode Python identifier validation.
• Soft-keyword context analysis.
• Python source-code parsing.

Unicode-complete Python identifier validation is future work.

Functions

is_ascii_python_identifier_continue

Returns whether character is accepted after the first identifier character.

is_ascii_python_identifier_start

Returns whether character is accepted as an ASCII Python identifier start.

is_dunder_name

Returns whether input looks like a Python dunder name such as __init__.
