rustHow to get all matches from a Rust regex?

To get all matches from a Rust regex, you can use the find_iter method on a Regex object. This method returns an iterator of Match objects, which can be used to access the matched text.

Example code

let re = Regex::new(r"\d+").unwrap();
let text = "123 456 789";

for m in re.find_iter(text) {
    println!("{}", m.as_str());
}

Output example

123
456
789

Code explanation

• Regex::new(r"\d+"): creates a new Regex object from the given regular expression.
• find_iter(text): returns an iterator of Match objects from the given text.
• m.as_str(): returns the matched text as a string.
