an example: let robot_name = Some(String::from("Bors")); match robot_name { Some(name) => println!("Found a name: {}", name), None => (), } println!("robot_name is: {:?}", robot_name); Listing 18-24: own- ership of the value This example will fail to compile since the value inside the Some value in robot_name is moved within the match when name binds to that value. Using & in a pattern matches an existing 18-25: 504 let robot_name = Some(String::from("Bors")); match robot_name { Some(ref name) => println!("Found a name: {}", name) , None => (), } println!("robot_name is: {:?}", robot_name); Listing
