Struct darklua_core::process::processors::FindVariables

pub struct FindVariables<'a> { /* fields omitted */ }

A processor to find usage of a given set of identifiers.

Example

The following example illustrate how you can use this processor to find usage of the foo variable.

let variables = vec!["foo".to_owned()];
let mut find_foo = FindVariables::from(&variables);

let mut foo_expression = Expression::Identifier("foo".to_owned());
DefaultVisitor::visit_expression(&mut foo_expression, &mut find_foo);

assert!(find_foo.has_found_usage());

If you pass a node that does not contain the given variable, the processor will return false when calling the has_found_usage() method.

let mut bar_expression = Expression::Identifier("bar".to_owned());
DefaultVisitor::visit_expression(&mut bar_expression, &mut find_foo);

assert!(!find_foo.has_found_usage());
