rell.get_app_structure(): map<text, gtv>​

Shows how your Rell dapp is built, revealing its modules and definitions. Definitions are entities, objects, structs, enums, operations, queries and functions.

Returns:

  • The type of the return value is GTV. Attributes (values) of entities, objects, structs and enums are returned as an array.

    Rell code example:

        struct module_args {
            x: integer;
            y: text;
        }

    Corresponding app structure example (fragment):

        {
            "structs": {
                "module_args": {
                    "attributes": [
                        { "mutable": 0, "name": "x", "type": "integer" },
                        { "mutable": 0, "name": "y", "type": "text" }
                    ]
                }
            }
        }
