What are some effective error handling techniques in Rust?

In Rust, common error handling techniques include using the Result and Option types, and the ? operator for propagation.

Can you explain how the Result type works?

The Result type is an enum that can be either Ok(T) for success or Err(E) for an error, allowing you to handle errors explicitly.

What about the Option type? How is it different?

The Option type represents a value that can be either Some(T) or None, used for cases where a value may be absent.

How do I use the ? operator in error handling?

The ? operator simplifies error handling by returning early from a function if the result is an Err, making code cleaner.
