there isn't a clear way to use them. The `tracing` library in Rust doesn't have an equivalent of this, instead futures re-enter and re-exit regular spans whenever they are polled. For us in OCaml the equivalent is to create a regular span whenever we schedule a future/fiber, and exit it when we yield.
