During a Rhai script callback functions' execution, our application would like to create and maintain additional values as global variables that can be later used by other router request lifecycles
fn subgraph_service(service, subgraph){
let v = Router.EXTRA_VARIABLE;
let f = |request| {
print(v);
};
service.map_request(f);
Router.EXTRA_VARIABLE++;
}
Describe alternatives you've considered
A coprocessor can achieve this but we would like to use Rhai to improve performance by minimizing communication costs between the coprocessor and the router

Currently, Rhai's support for global variables is limited to only things that are maintained by
