What are some popular async libraries in Rust?

Some popular async libraries in Rust include Tokio, async-std, and smol. They help with asynchronous programming.

Can you explain how Tokio works?

Tokio is an asynchronous runtime for Rust that provides the building blocks for writing reliable network applications. It uses a multi-threaded scheduler to run tasks concurrently.

What are the differences between Tokio and async-std?

Tokio is more feature-rich and has a larger ecosystem, while async-std aims for simplicity and ease of use, closely resembling the standard library.

Are there any performance benchmarks comparing these libraries?

Yes, there are benchmarks available that compare the performance of Tokio, async-std, and smol. Generally, Tokio tends to perform better in high-load scenarios.
