rust split string into words

To split a string into words in Rust, you can utilize the split_whitespace method provided by the str type. Here's an example:

fn main() {
    let sentence = "Hello, world! This is a sentence.";
    let words: Vec<&str> = sentence.split_whitespace().collect();
    println!("{:?}", words);
}

The split_whitespace method splits the string into words based on whitespace characters (spaces, tabs, newlines, etc.). It returns an iterator over the words, which we can collect into a Vec<&str> to store each word separately. In the example above, the output will be ["Hello,", "world!", "This", "is", "a", "sentence."].

You can modify this example to suit your specific needs.
