Hi,
What would be the Erlang equivalent for the with special form like:
with {:ok, width} <- Map.fetch(opts, :width),
{:ok, height} <- Map.fetch(opts, :height) do
{:ok, width * height}
else
:error -> {:error, :wrong_data}
end
I’m switching back and forth between the languages and still didn’t found a nice abstraction in Erlang for this.
Thanks,
