How is state saving and loading supposed to work? I see that there are 2 methods avail

To make life easier I have written following extension method: <div class="highlig

There are many ways of storing the state of the state machine so I don't provide a default implementation.
Luckily, implementing the interfaces for loading and saving is quite easy. Some docu: https://github.com/appccelerate/statemachine/blob/nullable_reference_types/documentation/persistence.md

I hope that helps.

To make life easier I have written following extension method:

    public static class AsyncStateMachineExtensions
    {
        public static async Task<StateMachineSaver<T, U>> SaveExt<T, U>(
            this AsyncPassiveStateMachine<T, U> machine)
            where T : IComparable
            where U : IComparable
        {
            var saver = new StateMachineSaver<T, U>();
            await machine.Save(saver);
            return saver;
        }

        public static async Task LoadExt<T, U>(
            this AsyncPassiveStateMachine<T, U> machine, 
            StateMachineSaver<T, U> saver)
                where T : IComparable
                where U : IComparable
        {
            var loader = new StateMachineLoader<T, U>();
            loader.SetCurrentState(saver.CurrentStateId);
            loader.SetEvents(saver.Events);
            loader.SetHistoryStates(saver.HistoryStates);
            loader.SetPriorityEvents(saver.PriorityEvents);

            await machine.Load(loader);
        }
    }
