How do I handle errors in Rust using async-std?

In Rust, you can handle errors in async-std by using the Result type. You can use the ? operator to propagate errors.

Can you show me a code example?

Sure! Here's a simple example:

use async_std::task;

async fn might_fail() -> Result<(), String> {
    Err("An error occurred".to_string())
}

fn main() {
    task::block_on(async {
        match might_fail().await {
            Ok(_) => println!("Success!"),
            Err(e) => println!("Error: {}", e),
        }
    });
}

What if I want to handle multiple errors?

You can define custom error types and use enums to represent different error cases. This way, you can match on the specific error type.
