  An iterator over the field values of a tuple struct.
• TupleStructInfo
  A container for compile-time tuple struct info.
• TupleVariantInfo
  Type info for tuple variants.
• TypePathTable
  Provides dynamic access to all methods on TypePath.

  Runtime storage for type metadata, registered into the TypeRegistry.
• TypeRegistry
  A registry of reflected types.
• TypeRegistryArc
  A synchronized wrapper around a TypeRegistry.

  Type info for unit variants.
• UnnamedField
  The unnamed field of a reflected tuple or tuple struct.
• ValueInfo
  A container for compile-time info related to general value types, including primitives.
