Option / Result / Vec / typle : basically we are interested in only inner values of the container

Code Block

[
{
    "typedefinition": "Option",
    "item_type": {
        "typedefinition" : "bool"
    }

},
{
    "typedefinition": "Result",
    "item_type": {
        "typedefinition": "int",
        "mode": "CompactFourByte"
    }
},
{
    "typedefinition": "Vec",
    "item_type": {
        "typedefinition": "bool"
    }
},
{
    "typedefinition": "tuple",
    "items": [
        {
            "typedefinition": "int",
            "mode": "CompactFourByte"
        },
        {
            "typedefinition": "Option",
            "item_type": {
                "typedefinition" : "bool"
            }
        
        }
    ]
}
]

3. Custom containers

Structures: in structures definitions declared inline for built-in types and declared a reference for custom types

Code Block

language	bash

{
    "typedefinition": "struct",
    "name": "Foo",
    "codec": "SCALE", //possible values SCALE or JSON
    "properties": [
        {
            "name": "enabled", //optional name
            "definitiontype": {
                "typedefinition": "bool"
            }
        },
        {
            "name": "id", //optional name
            "definitiontype": {
                "typedefinition": "struct", //reference to other struct
                "struct_name": "Id"
            }
        },
        {
            "name": "counter", //optional name
            "definitiontype": {
                "typedefinition": "int",
                "mode": "FixedWidth"
            }
        }
    ]
}

Enums: similar to Structures but also every variant of enum has a discriminator that used in Scale. By default based on 0, but can be overridden by attributes

Code Block

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

Concerns

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