own_and_return

Instructions

Create a struct Film that has one field name of type String.

Create the following two functions:

• Create a function take_film_name it will return the name and consume the film (you should not be able to reuse it after you passed it to the function).
• Create a function read_film_name it will return the name without consuming the film (you can call the function multiple times with the same argument).

Expected functions

pub struct Film {
    pub name: String,
}

pub fn read_film_name(/* to be implemented */) -> String {
}

pub fn take_film_name(/* to be implemented */) -> String {
}

Usage

Here is a possible program to test your function :

use own_and_return::*;


pub struct Film {
    pub name: String,
}

fn main() {
    let my_film = Film { name: "Terminator" };
    println!("{}",  take_film_name(/* to be implemented */);
    println!("{}",  read_film_name(/* to be implemented */);
}

And its output:

$ cargo run
Terminator
Terminator
Terminator
$
