Context properties

Hey, I am just trying to port (I guess) some moleculer service from Javascript, granted I know just a basics in Rust and in general I am below the 10k lines ever written, so pardon if the question is stupid.

However in the moleculer-js, you can assing certain parameters to context
https://moleculer.services/docs/0.14/context.html

it does not appear to be the case in your Rust implementation, I know that due to borrow checker, this might not be possible, especially with tokio threading.

But I would still like to ask if I could get some assistance how to do this:

I have this piece of code:

broker.createService({
  name: config.id,
  mixins: [Request],
  dependencies: ['blockchainRegistry', 'paymentGateway'],
  events: {
    ping: {
      handler(ctx) {
        const nowTime = new Date().getTime();
        const delay = nowTime - ctx.params.datetime;
        return ctx.broadcast('pong', { service_prefix: ctx.name, datetime: nowTime, delay });
      },
    },
    "currency.created": {
      async handler(ctx) {
        ctx.options.coin = await ctx.call('paymentGateway.getPICoin', {paymentInterfaceId: config.id});
      }
    }
  },
  actions,

  created() {
		this.broker.metrics.register({ 
			type: "info", 
			name: "process.converter.version", 
			description: "Converter version", 
		});

		this.broker.metrics.set("process.converter.version", packageJSON.version)
	},
  async started() {
    console.log('STARTED+++++');
    const _self = this;
    
  },
  stopped() {
    console.log("=>>>>>>>>>>>> BROKER STOPPED");
    //broker.call('blockchainRegistry.unregister', {});
  }
});

I figure out most of it, but the currency.created event is beyond my knowledge, since global variables is tricky think to do, do you know any way, how could I store the info, which should go to ctx.options.coin?

Thanks and sorry for being newbie.
