The ArrowFunctionExpression AST node.

Fields

metadata: NodeMetadata<'gc>

Source range, debug location, paren count, and node id.

params: NodeList<'gc>

ESTree params property.

body: &'gc Node<'gc>

ESTree body property.

type_parameters: Option<&'gc Node<'gc>>

ESTree typeParameters property.

return_type: Option<&'gc Node<'gc>>

ESTree returnType property.

predicate: Option<&'gc Node<'gc>>

ESTree predicate property.

expression: Cell<bool>

ESTree expression property.

async: Cell<bool>

ESTree async property.

scope: Cell<Option<SemaId>>

Sema: the lexical scope created by this node, if any.

sem_info: Cell<Option<SemaId>>

Sema: FunctionInfo for this function.

strictness: Cell<Strictness>

Sema: strict-mode state of this function.

is_method_definition: Cell<bool>

Whether this function is a method definition (getters and setters included) rather than a function. Used for lazy reparsing.

decorations: Cell<NodeList<'gc>>

Decorations attached to this function by Hermes.decorate(...) calls in typed mode; each entry wraps a decoration expression.

Implementations

impl<'gc> ArrowFunctionExpression<'gc>

pub fn new( metadata: NodeMetadata<'gc>, params: NodeList<'gc>, body: &'gc Node<'gc>, type_parameters: Option<&'gc Node<'gc>>, return_type: Option<&'gc Node<'gc>>, predicate: Option<&'gc Node<'gc>>, expression: bool, async: bool, ) -> Self

Build ArrowFunctionExpression from its metadata and ESTree.def fields. Decoration fields start at their defaults.

Trait Implementations

impl<'gc> Debug for ArrowFunctionExpression<'gc>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
