How to Append a String to another String in Rust ?

To append a string to another string in Rust, you can use the format! macro or the push_str method of the String type.

In this example,

fn main() {
    let str1 = String::from("Hello");
    let concatenated = format!("{} World", str1);
    println!("{}", concatenated);
}

Hello World

In this example,

We create a string named mut str2 with a value of "banana".
We then use the push_str method to append the string "apple" to str2.
The push_str method concatenates the two strings and modifies the original str2.
Finally, we print the concatenated string to the console.

fn main() {
    let mut str2 = String::from("banana");
    str2.push_str("apple");
    println!("{}", str2);
}

bananaapple
