rustHow do I append a string in Rust?

You can append a string in Rust using the push_str() method. This method takes a string slice as an argument and appends it to the end of the string.

Example code

let mut s = String::from("Hello ");
s.push_str("World!");

Output example

Hello World!

Code explanation

• let mut s = String::from("Hello ");: This line creates a mutable String variable s and assigns it the value Hello.
• s.push_str("World!");: This line calls the push_str() method on the s variable, passing in the string World! as an argument. This appends the string World! to the end of the s variable.
