You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: no_misrefactored_shorthand_assign.rs
    path of file: ./repos/biome/crates/biome_js_analyze/src/analyzers/suspicious
    
    the code of the file until where you have to start completion: use biome_analyze::{
    context::RuleContext, declare_rule, ActionCategory, Ast, FixKi
    
    fn run(ctx: &RuleContext<Self>) -> Self::Signals {
        let node = ctx.query();

        if matches!(node.operator(), Ok(JsAssignmentOperator::Assign)) {
            return None;
        }

        let right = node.right().ok()?;
        let operator = node.operator_token().ok()?;
        let operator = operator.text_trimmed();
        let operator = &operator[0..operator.len() - 1];

        let binary_expression = match right {
            AnyJsExpression::JsBinaryExpression(binary_expression) => binary_expression,
            AnyJsExpression::JsParenthesizedExpression(param) => {
                JsBinaryExpression::cast_ref(param.expression().ok()?.syntax())?
            }
            _ => return None,
        };

        let bin_operator = binary_expression.operator_token().ok()?;
        let bin_operator = bin_operator.text_trimmed();

        let not_same_operator_from_shorthand = operator != bin_operator;

        if not_same_operator_from_shorthand {
            return None;
        }

        let left = node.left().ok()?;
        let left = left.as_any_js_assignment()?;
        let left_text = left.text();

        let variable_position_in_expression =
            find_variable_position(&binary_expression, &left_text)?;

        if !binary_expression.operator().ok()?.is_commutative()
            && matches!(variable_position_in_expression, VariablePosition::Right)
        {
            return None;
        }

        match variable_position_in_expression {
            VariablePosition::Left => binary_expression.right(),
            VariablePosition::Right => binary_expression.left(),
        }
        .ok()
    }
