An example of an AI chatbot conversation about error handling with futures in Rust.
How can I handle errors when using futures in Rust?
In Rust, you can handle errors in futures using the Result type. You can use combinators like map_err to transform errors.
Can you give me an example of using map_err?
Sure! Here's a simple example:
let future = async {
// some operation that may fail
};
let result = future.map_err(|e| e.to_string()).await;
What if I want to handle multiple futures?
You can use join or try_join from the futures crate to handle multiple futures and their errors.
