Struct Variable 

pub struct Variable { /* private fields */ }

Variable represents a variable declaration of some kind.

For let and const declarations this type represents a LexicalBinding

For var declarations this type represents a VariableDeclaration

Implementations

impl Variable

pub const fn from_identifier( ident: Identifier, init: Option<Expression>, ) -> Variable

Creates a new variable declaration from a BindingIdentifier.

pub const fn from_pattern( pattern: Pattern, init: Option<Expression>, ) -> Variable

Creates a new variable declaration from a Pattern.

pub const fn binding(&self) -> &Binding

Gets the variable declaration binding.

pub const fn init(&self) -> Option<&Expression>

Gets the initialization expression for the variable declaration, if any.

Trait Implementations

impl Clone for Variable

fn clone(&self) -> Variable

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Variable

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Variable

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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

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

Converts to this type from the input type.

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

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

Converts to this type from the input type.

impl PartialEq for Variable

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

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 Variable

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

Converts a given element to a string using an interner.

impl VisitWith for Variable

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.
