How to get list of event eligible events?

[gamesover]

event :start do
       transition :parked => :in_motion
    end

    event :stop do
       transition :in_motion => :parked
    end

    state(:in_motion, value: 0)

I want to get the list of eligible states, such as
MyClass.state_machine.events[:stop][:from], get result of [0]

I don't know if that is possible.

MyClass.state_machine.events[:stop].branches.flat_map(&:state_requirements).flat_map { |sr| sr[:from].description }.uniq
Something like this could help but there is a Problem mit StateMachines::BlacklistMatchers
