Equivalent of Vertx RoutingContext.put() for storing variables?

[javadevmtl]

So I have been using Vertx since almost version 1. I have extensively built my platform on Vertx and now looking to using Quarkus a bit more. I have less experience with Jax-Rs a/RestEasy.

Quarkus is quite opinionated compared to Vertx and trying to find ways to fit all the un-opinionated stuff back into Quarkus...

One thing I do with Vertx is when someone access a web resource endpoint such as /hello/world/

In Vertx I can access the RoutingContext and put() a variable in the context and then access it downstream on chained handlers (filters).

I do this mostly for storing variables and things I want to pass to a Loging filter.

So I know there quarkus-vertx-reactive-routes and I can access the RC there directly. But wondering what would be the equivalent on the new quarkus-resteasy-reactive extension.

I know I can use Request and Response context and filters. But which of the context is the correct one to store/share a variable and read it down stream on a filter that execute after the endpoint is called?

Edit: I see for filters we can use: ContainerRequestContext.setProperty and getProperty, but how do you access it on the actuall resource?

    @Path("/hello")
    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public void hello (){
        System.out.println("Hello world!");

        // How do we set or get a property here?
    }
