Split in Rust 1.55

To split a string in Rust 1.55, you can use the split method of the str type. The split method takes a delimiter as an argument and returns an iterator that produces the substrings between the delimiters.

Here is an example code snippet that shows how to split a string on a space delimiter:

fn main() {
    let my_string = "Hello World";
    let tokens: Vec<&str> = my_string.split(" ").collect();
    println!("{:?}", tokens);
}

In this example, the split method is called on the my_string variable with a space delimiter as an argument. The collect method is then called on the iterator that is returned by split to collect the substrings into a Vec<&str>.

The resulting Vec contains two elements: "Hello" and "World", which are the substrings between the space delimiter.

You can also use other delimiters like commas or semicolons:

fn main() {
    let my_string = "apple,banana,kiwi";
    let tokens: Vec<&str> = my_string.split(",").collect();
    println!("{:?}", tokens);
}

This code snippet splits the string on commas and produces a Vec with three elements: "apple", "banana", and "kiwi".
