A representation of a kind of Value. Most variants just represent the corresponding Value variants.

The below associated functions return cloned Arcs to defaults.

Variants

None

Null type, only to be used internally. For external code, use an Option.

Any

Used by generics to accept any type. This is available as _ but generally prefer generic instead.

Type

Reference

Number

String

List(Arc<Type>)

Map(Arc<Type>, Arc<Type>)

Enum(Arc<Vec<(String, Arc<Type>)>>)

Struct(Arc<HashableMap<String, Arc<Type>>>)

Generic(Arc<Type>, Arc<HashableMap<String, Arc<Type>>>)

A pair of the underlying type and a map of generic parameter types.

This doesn’t correspond to a Value variant since the actual type it should act as is valid.

Trait Implementations

impl Clone for Type

fn clone(&self) -> Type
