How to split a string multiple times in Rust?

Question

With a string like "1 foo\n2 bar\n3 foobar", how do I split it into:

[["1", "foo"], ["2", "bar"] ["3", "foobar"]]

Answer 1

This will work.

fn main() {
    let string: Vec<Vec<&str>> = "1 foo\n2 bar\n3 foobar".split('\n')
        .map(|x: &str| x.split(' ').collect())
        .collect();
    println!("{:?}", string);
}
