  Code Block
  { "type": "enum", "name": "Bar", "codec": "SCALE", //possible values SCALE or JSON "variants": [ { "name": "FirstVariant", "discriminator": 1, "properties": { ... } }, { "name": "SecondVariant", "discriminator": 2, "properties": { ... } } ] }

Currently we are not support polymorphism via TraitObjects, but it can be implemented if necessary
