What are async iterators in Rust and how do they work?

Async iterators in Rust allow you to work with asynchronous streams of data, enabling non-blocking operations.

Can you give me an example of how to implement an async iterator?

Sure! You can implement an async iterator by defining a struct that implements the Stream trait and using async fn.

What are some use cases for async iterators?

They are useful for handling data streams, such as reading from files or network sockets, without blocking the thread.

Are there any libraries in Rust that support async iterators?

Yes, libraries like tokio and async-std provide support for async iterators and streams.
