rustrust string append char

Rust strings are immutable, meaning that once created, they cannot be changed. However, it is possible to append a single character to a string using the push method.

Example code

let mut s = String::from("Hello");
s.push('!');

Output example

Hello!

The code above creates a mutable string s with the value Hello. The push method is then used to append the character ! to the end of the string. The result is the string Hello!.
