How to deal with errors gracefully in map method of Option?

Question

In the Rust By Example book show us a way to handle errors in the map method of Iterator:

    let strings = vec!["93", "tofu", "18"];
    let numbers: Result<Vec<_>, _> = strings.into_iter().map(|s| s.parse::<i32>()).collect();
    println!("Results: {:?}", numbers);

Is it a similar way to deal with errors in Option like the following?

    let a: Option<&str> = Some("tofu");
    let b: Result<Option<i32>, _> = a.map(|a| a.parse::<i32>());
    println!("Results: {:?}", b);
