pub fn python_parameter_label_node(node: Node<'_>) -> Option<Node<'_>>Expand description
The identifier node that names one parameter’s binding.
The grammar gives default_parameter and typed_default_parameter a
name field but gives typed_parameter and the two splat patterns none,
so a caller that reads only the field loses the binding name of every
annotated parameter. Every Python surface that names parameters reads them
through this function.
