Unknown type public_key:ec_public_key/0

[martinos]

I am new to elixir and I try to use a typespec for one of my function.

  @spec fetch_key(String.t()) :: {:ok, X509.PublicKey.t()} | {:error, any()}
  def fetch_key(url) do
    CertValidation.fetch_valid_pub_key(url)
  end

When I run dialyzer I get the following error message:

:0: Unknown type public_key:ec_public_key/0
:0: Unknown type public_key:rsa_public_key/0

Do you have an idea of what might be the issue?

Yes, this is a known issue (see #22). As I mentioned there, :public_key does not expose the types used in the docs, and I wanted to use those types in my docs to stress the compatibility with the native types used in :public_key and :ssl.

This may get resolved as part of the extraction of core functionality to an Erlang package.
