Erlang gen_statem module documentation "state_functions" callback mode example "translated" to Elixir
# file: pushbutton.ex
# Translated from: http://erlang.org/doc/man/gen_statem.html#example
# callback mode: :state_functions
# i.e. one callback function per state, so the each possible
# state has to be represented as a bare atom which directly
# identifies the module function to be called (:gen_fsm like).
#
# This example has two states :on and :off.
# Therefore there is an on/3 and an off/3 callback function.
