# `Dialyxir.Warnings.CallbackMissing`
[🔗](https://github.com/jeremyjh/dialyxir/blob/1.4.8/lib/dialyxir/warnings/callback_missing.ex#L1)

Module implements a behaviour, but does not have all of its
callbacks. This is also a compiler warning.

## Example

    defmodule ExampleBehaviour do
      @callback ok() :: :ok
      @callback missing() :: :ok
    end

    defmodule Example do
      @behaviour ExampleBehaviour

      def ok() do
        :ok
      end
    end
