What are the differences between Tokio and Async-Std in Rust?

What are the main differences between Tokio and Async-Std in Rust?

Tokio and Async-Std are both asynchronous runtimes for Rust, but they have different design philosophies. Tokio is more performance-oriented and provides a rich ecosystem of libraries, while Async-Std aims for simplicity and ease of use, resembling the standard library.

Which one should I choose for my project?

It depends on your project's needs. If you require high performance and are building a complex application, Tokio might be the better choice. If you prefer a simpler API and are working on a smaller project, Async-Std could be more suitable.

Can I use both in the same project?

Using both in the same project is possible, but it can lead to complications. It's generally recommended to stick to one runtime to avoid potential issues with compatibility and performance.

What are some libraries available for each?

For Tokio, you have libraries like Tokio-Timer, Tokio-IO, and Hyper. For Async-Std, you can use libraries like Async-Std itself, Surf for HTTP requests, and async-std-io for asynchronous I/O operations.
