unwrap!(result, opts \\ nil)

View Source

Raises an error if the result is an error, otherwise returns the result

Alternatively, you can use the defsplode macro, which does this automatically.

Options

  • :error_opts - Options to pass to to_error/2 when converting the returned error
  • :unknown_error_opts - Options to pass to the unknown error if the function returns only :error. not necessary if your function always returns {:error, error}.

Examples

def function(arg) do

case do_something(arg) do
  :success -> :ok
  {:success, result} -> {:ok, result}
  {:error, error} -> {:error, error}
end

end

def function!!(arg) do

YourErrors.unwrap!(function(arg))

end
