What are futures in Rust?
Futures in Rust are a way to handle asynchronous programming, allowing you to work with values that may not be available yet.
How do I create a future in Rust?
You can create a future using the async
keyword and the await
syntax to handle the result when it's ready.
Can you give me an example of using futures?
Sure! Here's a simple example: async fn fetch_data() -> String { ... }
and you can call it with let result = fetch_data().await;
.
