Function get_subscriber 

pub fn get_subscriber(
    name: String,
    env_filter: String,
    sink: impl MakeWriter + Send + Sync + 'static,
    endpoint_url: &str,
) -> impl Subscriber + Sync + Send

Compose multiple layers into a tracing’s subscriber.

Implementation Notes

We are using impl Subscriber as return type to avoid having to spell out the actual type of the returned subscriber, which is indeed quite complex.
