This makes the
--worker_threadsCLI argument default toNone. If no argument is passed, then the tokio runtime will use as many threads as there are cores. The number of cores is obtained viastd::thread::available_parallelism().According to the docs,
available_parallelismcan return an error, for example if the amount of parallelism is not known to the target platform, or the program lacks permission to query the amount of parallelism.This should never happen, but in this case the number of threads will default to 4.
