rustrust string clone


String::clone is a method in Rust that creates a new String from an existing one. It is used to create a deep copy of a String so that the original String can be modified without affecting the new one.

Example

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

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

Output example

s1 = Hello, s2 = Hello

The code above creates two Strings, s1 and s2, from the same string literal. s2 is created using the clone method on s1. This creates a deep copy of s1 so that modifying s1 does not affect s2.

Parts of the code:

  • let s1 = String::from("Hello");: This creates a String from the string literal "Hello".
  • let s2 = s1.clone();: This creates a deep copy of s1 and assigns it to s2.
  • println!("s1 = {}, s2 = {}", s1, s2);: This prints out the values of s1 and s2.
