Enum Js 

pub enum Js {
    Undefined,
    Null,
    Bool(bool),
    Num(f64),
    Str(String),
    Arr(Vec<Js>),
    Obj(Obj),
    Typed(Typed, Arc<Vec<u8>>),
    Blob(String, Arc<Vec<u8>>),
}

A JavaScript value as a row holds it.

Variants

Undefined

undefined: left out of an object, null in an array (as JSON.stringify does).

Null

Bool(bool)

Num(f64)

Str(String)

Arr(Vec<Js>)

Obj(Obj)

Typed(Typed, Arc<Vec<u8>>)

A typed array, as its little-endian bytes.

Blob(String, Arc<Vec<u8>>)

A Blob of the given media type.
