 * @name Struct
 * @description
 * A Struct defines an Object with key-value pairs - where the values are Codec values. It removes
 * a lot of repetition from the actual coding, define a structure type, pass it the key/Codec
 * values in the constructor and it manages the decoding. It is important that the constructor
 * values matches 100% to the order in th Rust code, i.e. don't go crazy and make it alphabetical,
 * it needs to decoded in the specific defined order.
