WebA Tokio task is an asynchronous green thread. They are created by passing an async block to tokio::spawn. The tokio::spawn function returns a JoinHandle, which the caller may use to interact with the spawned task. The async block may have a return value. The caller may obtain the return value using .await on the JoinHandle. WebAsynchronous programs in Rust are based around lightweight, non-blocking units of execution called tasks. The tokio::task module provides important tools for working with tasks: The spawn function and JoinHandle type, for scheduling a new task on the Tokio runtime and awaiting the output of a spawned task, respectively,
