## Caso de uso

Por exemplo, imagine que você deseja retornar um código de status HTTP de "OK" `200` por padrão.

Mas se o dado não existir, você quer criá-lo e retornar um código de status HTTP de "CREATED" `201`.

Mas você ainda quer ser capaz de filtrar e converter o dado que você retornará com um `response_model`.

Para estes casos, você pode utilizar um parâmetro `Response`.

## Use um parâmetro `Response`

func (set TargetIDSet) Difference(sset TargetIDSet) TargetIDSet {
	nset := NewTargetIDSet()
	for k := range set {
		if _, ok := sset[k]; !ok {
			nset.add(k)
		}
	}

	return nset
}

// NewTargetIDSet - creates new TargetID set with given TargetIDs.
func NewTargetIDSet(targetIDs ...TargetID) TargetIDSet {
	set := make(TargetIDSet)
	for _, targetID := range targetIDs {
		set.add(targetID)
	}
	return set
