rustrust string copy

A Rust String can be copied using the clone() method. This method creates a new String with the same contents as the original.

Example

let s1 = String::from("Hello World!");
let s2 = s1.clone();

println!("s1 = {}, s2 = {}", s1, s2);

Output example

s1 = Hello World!, s2 = Hello World!

The clone() method:

• Creates a new String with the same contents as the original.
• Allocates memory for the new String on the heap.
• Copies the contents of the original String into the new String.
