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>, ) -> Self

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

Gets the variable declaration binding.

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