Enum Binding 

pub enum Binding {
    Object {
        fields: Vec<ObjectPatternField>,
        rest: Option<Ident>,
        span: Span,
    },
    Array {
        elems: Vec<Option<Ident>>,
        defaults: Vec<Option<ExprId>>,
        rest: Option<Ident>,
        span: Span,
    },
}

Destructuring binding pattern. Plain Ident bindings stay as Let/Const stmts; only {…} / […] forms appear here.

Variants

Object

Fields

fields: Vec<ObjectPatternField>

rest: Option<Ident>

Array

Fields

elems: Vec<Option<Ident>>

None entries are holes ([, x]).

defaults: Vec<Option<ExprId>>

Defaults at the corresponding element positions; holes have no default.

rest: Option<Ident>

span: Span
