Split a string keeping the separators

Question

Is there a trivial way to split a string keeping the separators? Instead of this:

let texte = \"Ten. Million. Questions. Let\'s celebrate all we\'ve done tog         


        

Answer 1

Using str::match_indices:

let text = "Ten. Million. Questions. Let's celebrate all we've done together.";

let mut result = Vec::new();
let mut last = 0;
for (index, matched) in text.match_indices(|c: char| !(c.is_alphanumeric() || c == '\'')) {
    if last != index {
        result.push(&text[last..index]);
    }
    result.push(matched);
    last = index + matched.len();
}
if last < text.len() {
    result.push(&text[last..]);
}

println!("{:?}", result);

Prints:

["Ten", ".", " ", "Million", ".", " ", "Questions", ".", " ", "Let\'s", " ", "celebrate", " ", "all", " ", "we\'ve", " ", "done", " ", "together", "."]
