Types

type Iterator

type Iterator interface {

	Pair() *Pair
}

func New

func New(ch chan *Pair) Iterator

type Pair

	Key   interface{}
	Value interface{}
}

	Iterate(context.Context) Iterator
}

	Visit(interface{}, interface{}) error
}

Visitor represents an object that handles each pair in a map
