Question: Determining which worker ID that a task is running on

[mmstick]

Is there a means to get the ID of a worker that is spawned on a Runtime?

oneshot::spawn_fn(
    || {
        eprintln!("processing on worker {}", ???);
        doing_thing()
    },
    &DefaultExecutor::current()
)

This is not possible. Why do you need to get the ID of the worker? Is it just for debugging or do you have another use case in mind?

[mmstick]

Debugging is one use case, as is displaying to the end user that tasks are being processed on multiple threads.

I think the right way to provide this info for debugging will be via Tokio trace here.

Tracking this in #1186.
