Module threading 

Modules

thread_primitives

This module provides all of the primitives needed to build a multithreaded application.

threading_functions

This module contains a few helper.

threading_macros

Main API for interacting with the threading back end. Remember, we use tokio as our executor. This means that by default, all jobs sent to the thread pool have to be async in nature. These macros make handling of these jobs at the sync/async boundary more convenient.
