ownership ergonomic in practice. Methods with More Parameters Let’s practice using methods by implementing a second method on the Rectangle struct. This time, we want an instance of Rectangle to take another &Rectangle) -> bool { self.length > other.length && self.width > other. width } } Listing 5-14: Implementing the can_hold method on Rectangle that takes another Rectangle instance as a parameter When we own hasher from scratch; crates.io has libraries that others have shared that provide hashers implementing many common hashing algorithms. 191 Summary Vectors, strings, and hash maps will take you far
