Container Types

Type Name	Description
sequence<T>	Variable-length array with elements of type T
map<K, V>	Key-value pair collection with keys of type K and values of type V

Structs

struct Point {
    uint32 x;
    uint32 y;
};

Enums

enum Color {
    Red,
    Green,
    Blue
};

Interfaces

    void log(string message);
};

Union

enum Color {
    Red,
    Green,
    Blue
};

union ColorPoint switch(Color) {
    case Red:
        uint32 red_x;
        uint32 red_y;
    case Green:
        uint32 green_x;
        uint32 green_y;
    case Blue:
        uint32 blue_x;
        uint32 blue_y;
    default:
        uint32 default_x;
        uint32 default_y;
};
