Enum ForLoopInitializer 

pub enum ForLoopInitializer {
    Expression(Expression),
    Var(VarDeclaration),
    Lexical(ForLoopInitializerLexical),
}

A ForLoop initializer, as defined by the spec.

A ForLoop initializer differs a lot from an IterableLoopInitializer, since it can contain any arbitrary expression instead of only accessors and patterns. Additionally, it can also contain many variable declarations instead of only one.

Variants

Expression(Expression)

An expression initializer.

Var(VarDeclaration)

A var declaration initializer.

Lexical(ForLoopInitializerLexical)

A lexical declaration initializer.

Trait Implementations

impl Clone for ForLoopInitializer

fn clone(&self) -> ForLoopInitializer

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ForLoopInitializer

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ForLoopInitializer

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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

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

Converts to this type from the input type.

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

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

Converts to this type from the input type.

impl From<Expression> for ForLoopInitializer

fn from(expr: Expression) -> ForLoopInitializer

Converts to this type from the input type.

impl From<LexicalDeclaration> for ForLoopInitializer

fn from(list: LexicalDeclaration) -> ForLoopInitializer

Converts to this type from the input type.

impl From<VarDeclaration> for ForLoopInitializer

fn from(list: VarDeclaration) -> ForLoopInitializer

Converts to this type from the input type.

impl PartialEq for ForLoopInitializer

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

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 ForLoopInitializer

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

Converts a given element to a string using an interner.

impl VisitWith for ForLoopInitializer

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.
