:arrows_counterclockwise:Futures and the future trait represent the return type of async functions.
:knife_fork_plate:Tokio is a popular async runtime for executing async code in Rust.
:gear:Tokio tasks allow top-level futures to be executed concurrently.
:stopwatch:Async code uses cooperative scheduling instead of preemptive scheduling.
How does async/await work in Rust?
—Async/await in Rust allows for writing asynchronous code that looks synchronous. The async keyword is used to define asynchronous functions, and the await keyword is used to pause the execution until a future completes.
What is the future trait in Rust?
—The future trait in Rust represents the return type of asynchronous functions. It defines the behavior of asynchronous computations and allows them to be composed and executed.
What is Tokio in Rust?
—Tokio is a popular runtime for executing asynchronous code in Rust. It provides a task scheduler, I/O handling, and other utilities for building concurrent and async applications.
What are Tokio tasks in Rust?
—Tokio tasks are lightweight non-blocking units of execution in Rust. They allow top-level futures to be executed concurrently, enabling parallelism in async code.
How does cooperative scheduling work in async code?
—Cooperative scheduling is used in async code to yield execution control at certain points defined by the developer. This allows other async tasks to run while waiting for a future to complete, improving efficiency and resource utilization.
00:00This video explains the async/await model in Rust, which allows for writing asynchronous code that looks synchronous.

08:41Tokio tasks allow top-level futures to be executed concurrently, enabling parallelism in async code.
11:46Async code uses cooperative scheduling, where developers yield execution control at specific points to allow other async tasks to run.
