Nim如何定义构造函数?

Nim how to define constructors?

Nim 有没有办法为对象定义构造函数? 例如我有

type Deck* = ref object
    cards* : array[52, Card]

我可以创建一个自动创建所有卡片的空构造函数吗?

type
  Card = int
  Deck* = ref object
    cards* : array[52, Card]

proc newDeck: Deck =
  new result
  for i, c in result.cards.mpairs:
    c = i
