To use this method, you’ll need to first import the `to_lowercase()` method from the `unicode` crate. Here’s an example of how to do that:
Once you’ve imported the method, you can use it on any string variable like this:
let my_string = "HELLO WORLD".to_lowercase();
This will convert the string “HELLO WORLD” to “hello world”.
It’s important to note that the `to_lowercase()` method only works on ASCII characters. If you need to convert non-ASCII characters to lowercase, you’ll need to use a different method.
Overall, using Rust’s built-in `to_lowercase()` method is a simple and effective way to convert strings to lowercase.
