Especializações

Ambas as especializações personalizados e sobrecargas do algoritmo std::swap são permitidos, mas as sobrecargas são geralmente preferidos desde especializações de um modelo de função não são permitidos para as classes de modelo. Funções da biblioteca sempre usar as sobrecargas fornecidos pelo usuário quando a troca, se forem encontrados pelo argumento dependente de pesquisa (como por conceito Swappable).

Original:

Both custom specializations and overloads of the std::swap algorithm are allowed, but the overloads are generally preferred since specializations of a function template aren't allowed for template classes. Library functions always use the user-provided overloads when swapping, if they are found by argument-dependent lookup (as per Swappable concept).
