Function cook

src/bin/error_option_unwrap_map.rs:31–33

Cooking food. Here, we showcase `map()` instead of `match` for case handling.

(chopped: Option<Chopped>)

// Cooking food. Here, we showcase `map()` instead of `match` for case handling.
fn cook(chopped: Option<Chopped>) -> Option<Cooked> {
    chopped.map(|Chopped(food)| Cooked(food))
}

// A function to peel, chop, and cook food all in sequence.
// We chain multiple uses of `map()` to simplify the code.
