An example of an AI chatbot conversation about optional types in Rust.
What are optional types in Rust?
Optional types in Rust, represented by Option<T>, allow you to express that a value may or may not be present.
How do I use Option<T> in my code?
You can use Option<T> to wrap values. For example, let x: Option<i32> = Some(5); or let y: Option<i32> = None;.
What are the benefits of using optional types?
They help prevent null pointer exceptions and make your code safer by explicitly handling the absence of values.
Can you show me an example of pattern matching with Option<T>?
Sure! You can use a match statement: match x { Some(v) => println!("Value: {}", v), None => println!("No value") };.
