Struct Evaluator 

pub struct Evaluator<'a> { /* private fields */ }

AST evaluator bound to a form-data tree and the current field path.

Implementations

impl<'a> Evaluator<'a>

pub fn new( form_data: &'a Value, current_path: &'a [String], row_keys: &'a [usize], ) -> Self

Build an evaluator over the full form data, the path of the field carrying the condition (including the field name itself) and the positions of the row keys in that path.

pub fn evaluate(&self, node: &Node) -> bool

Evaluate to a boolean condition result (JS evaluateCondition).

pub fn evaluate_value(&self, node: &Node) -> Value

Evaluate to a value (JS evaluateExpressionValue). A ternary returns its chosen branch’s RAW value; every other node returns its boolean condition result (the shared fixture’s value for non-ternary mirrors truthy).
