Struct Evaluator 

pub struct Evaluator { /* private fields */ }

Evaluator for JSONata expressions

Implementations

impl Evaluator

pub fn new() -> Self

pub fn with_context(context: Context) -> Self

pub fn with_options(context: Context, options: EvaluatorOptions) -> Self

Construct an Evaluator with guardrail options. Evaluator::new()/ with_context() remain unchanged (unlimited options) for existing callers.

pub fn evaluate( &mut self, node: &AstNode, data: &JValue, ) -> Result<JValue, EvaluatorError>

Evaluate an AST node against data

This is the main entry point for evaluation. It sets up the parent context to be the root data if not already set.

Also the single choke point for stripping any lingering tuple-stream wrapper objects ({"@":.., "__tuple__":true, ...}) from the result before it reaches the caller — %/@/# are implemented internally via a tuple-stream representation (see create_tuple_stream), and without this a bare (or object/array-nested) tuple-producing expression would leak that internal representation into user-visible output instead of the plain value.

Trait Implementations

impl Default for Evaluator

fn default() -> Self

Returns the “default value” for a type.
