elixir - 如何应对分组警告？

Question

有几个 def 组，当我写 @spec 时，它会收到 warning: clauses for the same def should be grouped together, def foo/2 was previously defined 警告。 。有什么解决办法吗？

虽然警告很有用，但我想让它忽略@spec。

@spec foo(:id, integer) :: {:not_found} | {:ok, String.t}
def foo(:id, id) do
  # some logic
end

@spec foo(:email, String.t) :: {:not_found} | {:ok, String.t}
def foo(:email, email) do
  # some logic
end

Answer 1

@spec foo(:id, integer) :: {:not_found} | {:ok, String.t}
@spec foo(:email, String.t) :: {:not_found} | {:ok, String.t}

def foo(:id, id) do
  # some logic
end

def foo(:email, email) do
  # some logic
end

或者您可以使用单个规范

@spec foo(:id | :email, integer | String.t) :: {:not_found} | {:ok, String.t}

我还没有测试过，但它应该可以工作。
