Enum LabelledItem 

pub enum LabelledItem {
    FunctionDeclaration(FunctionDeclaration),
    Statement(Statement),
}

The set of Parse Nodes that can be preceded by a label, as defined by the spec.

Semantically, a Labelled statement should only wrap Statement nodes. However, old ECMAScript implementations supported labelled function declarations as an extension of the grammar. In the ECMAScript 2015 spec, the production of LabelledStatement was modified to include labelled FunctionDeclarations as a valid node.

Variants

FunctionDeclaration(FunctionDeclaration)

A labelled FunctionDeclaration.

Statement(Statement)

A labelled Statement.

Trait Implementations

impl Clone for LabelledItem

fn clone(&self) -> LabelledItem

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for LabelledItem

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LabelledItem

fn deserialize<__D>( __deserializer: __D, ) -> Result<LabelledItem, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> From<&'a LabelledItem> for NodeRef<'a>

fn from(node: &'a LabelledItem) -> NodeRef<'a>

Converts to this type from the input type.

impl<'a> From<&'a mut LabelledItem> for NodeRefMut<'a>

fn from(node: &'a mut LabelledItem) -> NodeRefMut<'a>

Converts to this type from the input type.

impl From<FunctionDeclaration> for LabelledItem

fn from(f: FunctionDeclaration) -> LabelledItem

Converts to this type from the input type.

impl From<Statement> for LabelledItem

fn from(stmt: Statement) -> LabelledItem

Converts to this type from the input type.

impl PartialEq for LabelledItem

fn eq(&self, other: &LabelledItem) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for LabelledItem

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToInternedString for LabelledItem

fn to_interned_string(&self, interner: &Interner) -> String

Converts a given element to a string using an interner.

impl VisitWith for LabelledItem

fn visit_with<'a, V>( &'a self, visitor: &mut V, ) -> ControlFlow<<V as Visitor<'a>>::BreakTy>

where V: Visitor<'a>,

Visit this node with the provided visitor.

fn visit_with_mut<'a, V>( &'a mut self, visitor: &mut V, ) -> ControlFlow<<V as VisitorMut<'a>>::BreakTy>

where V: VisitorMut<'a>,

Visit this node with the provided visitor mutably, allowing the visitor to modify private fields.
