Variants§

§

AliasTo

For

  • extends interface part (for multiple it to is a Type::And)
  • Can be used for subtypes (aka N aliases number then more types on top)
  • **Does not imply .prototype = **

Fields

§name: String
§parameters: Option<Vec<TypeId>>
§

And(TypeId, TypeId)

§

Or(TypeId, TypeId)

§

RootPolyType(PolyNature)

§

Constructor(Constructor)

Also a “Substituted constructor type”

§

PartiallyAppliedGenerics(PartiallyAppliedGenerics)

**e.g Array<string>

§

Interface

For number and other rooted types

Although they all alias Object

Fields

§name: String
§nominal: bool
§parameters: Option<Vec<TypeId>>
§

Class

Pretty much same as Type::Interface

Fields

§name: String
§parameters: Option<Vec<TypeId>>
§

Constant(Constant)

Dependent equality types

§

FunctionReference(FunctionId)

From a type annotation or .d.ts WITHOUT body. e.g. don’t know effects TODO…

§

Object(ObjectNature)

Technically could be just a function but…

§

SpecialObject(SpecialObjects)
