Rtypes
Rtypes is a conceptual framework and set of language constructs for describing and enforcing runtime types in programming environments. It provides a separate layer of type metadata that accompanies values at runtime, enabling explicit checks, validation, and contract enforcement without relying solely on static type systems.
Definition and scope: An Rtype is a descriptor that encodes a type’s structure and semantics, including primitives
Core concepts: Type descriptors, type tags, and meta-objects; validation and coercion rules; subtyping and distinctions between
Architecture: Values carry a type descriptor that can be inspected at runtime. A runtime checker uses the
Use cases: Enforcing data contracts in APIs, validating user input, safe inter-process or network communication, dynamic
History and relationship to other concepts: The approach integrates with existing type systems by supplementing them
