Credo.Check.Readability.ImplTrue (Credo v1.6.0) View Source

This check has a base priority of normal and works with any version of Elixir.


When implementing behaviour callbacks, @impl true indicates that a function implements a callback, but a better way is to note the actual behaviour being implemented, for example @impl MyBehaviour. This not only improves readability, but adds extra validation in cases where multiple behaviours are implemented in a single module.

Instead of:

@impl true
def my_funcion() do


@impl MyBehaviour
def my_funcion() do
