Functions

Example

immutable base  = enumap(Element.water, 4, Element.air , 3);
immutable bonus = enumap(Element.water, 5, Element.fire, 2);

immutable sum  = base + bonus;
immutable diff = base - bonus;
immutable prod = base * bonus;

assert(sum.water == 4 + 5);
assert(sum.air   == 3 + 0);
assert(sum.fire  == 0 + 2);
assert(sum.earth == 0 + 0);

assert(diff.water == 4 - 5);
assert(diff.air   == 3 - 0);
assert(diff.fire  == 0 - 2);
assert(diff.earth == 0 - 0);

assert(prod.water == 4 * 5);
assert(prod.air   == 3 * 0);
assert(prod.fire  == 0 * 2);
assert(prod.earth == 0 * 0);

Example

    ItemType.junk  , [ "Gemstone"        ],
    ItemType.normal, [ "Sword", "Shield" ],
    ItemType.key   , [ "Bronze Key"      ]);

auto loot = enumap(
    ItemType.junk  , [ "Potato"       ],
    ItemType.normal, [ "Potion"       ],
    ItemType.key   , [ "Skeleton Key" ]);

inventory ~= loot;

assert(inventory.junk   == [ "Gemstone", "Potato"          ]);
assert(inventory.normal == [ "Sword", "Shield" , "Potion"  ]);
assert(inventory.key    == [ "Bronze Key" , "Skeleton Key" ]);
