rustHow do I append a character to a string in Rust?

You can append a character to a string in Rust using the push() method. This method takes a single character as an argument and adds it to the end of the string.

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

Output example

Hello!

The code above does the following:

1. Declares a mutable string s and assigns it the value Hello.
2. Calls the push() method on s with the argument !.
3. Prints the value of s to the console.
