Variants

Empty

A Tuple with no bindings

Tuple(&'a Tuple)

Holds a reference to a Tuple

Dynamic(&'a dyn RefTupleView<'a, Value>)

Holds a reference to a RefTupleView

CoercedValue(usize, &'a Value)

Holds a reference to a value which is not a tuple, but has been coerced (e.g., for 9: {'_1': 9})

SingleKey(Cow<'a, str>, &'a Value)

A reference to a value stored under a single key

Bindings(&'a HashMap<Cow<'a, str>, &'a Value>)

A reference to a value stored under a single key
