// include the latest version of the regex crate in your Cargo.toml
extern crate regex;
use regex::Regex;
fn main() {
let regex = Regex::new(r"(?m)\{\{c(\d{1,3}) [^}\n]*MPSC03P card:\1").unwrap();
let string = "{{c1 MPSC03P card:1
{{c50 MPSC03P card:50
{{c100 MPSC03P card:100
{{c999 MPSC03P card:999
fails if the numbers don't match:
{{c1 MPSC03P card:7
if this is an issue, it can be prevented but the approach depends on what comes after card:50:
{{c5 MPSC03P card:50";
// result will be an iterator over tuples containing the start and end indices for each match in the string
let result = regex.captures_iter(string);
for mat in result {
println!("{:?}", mat);
}
}
