Enum IterableLoopInitializer 

pub enum IterableLoopInitializer {
    Identifier(Identifier),
    Access(PropertyAccess),
    Var(Variable),
    Let(Binding),
    Const(Binding),
    Pattern(Pattern),
}

A for-in, for-of and for-await-of loop initializer.

The spec specifies only single bindings for the listed types of loops, which makes us unable to use plain LexicalDeclarations or VarStatements as initializers, since those can have more than one binding.

Variants

Identifier(Identifier)

An already declared variable.

Access(PropertyAccess)

A property access.

Var(Variable)

A new var declaration.

Let(Binding)

A new let declaration.

Const(Binding)

A new const declaration.

Pattern(Pattern)

A pattern with already declared variables.

Trait Implementations

impl Clone for IterableLoopInitializer

fn clone(&self) -> IterableLoopInitializer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IterableLoopInitializer

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for IterableLoopInitializer

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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

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

Converts to this type from the input type.

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

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

Converts to this type from the input type.

impl PartialEq for IterableLoopInitializer

fn eq(&self, other: &IterableLoopInitializer) -> 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 IterableLoopInitializer

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 IterableLoopInitializer

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

Converts a given element to a string using an interner.

impl VisitWith for IterableLoopInitializer

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.
