using System;
using Savvyio;
using Savvyio.Dispatchers;
using Savvyio.Handlers;

namespace ExampleApp;

public sealed class DispatcherWithValidation
{
    public void ValidateHandlerPresence<THandler>(IRequest request)
        where THandler : IHandler<IRequest>
    {
        try
        {
            throw OrphanedHandlerException.Create<IRequest, THandler>(request, "request");
        }
        catch (OrphanedHandlerException exception)
        {
            Console.WriteLine($"No handler found: {exception.Message}");
