WebbThere are a couple of different ways to share state in Tokio. Guard the shared state with a Mutex. Spawn a task to manage the state and use message passing to operate on it. Generally you want to use the first approach for simple data, and the second approach for things that require asynchronous work such as I/O primitives.
