// 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)^\d{2}(,\d{2})*$").unwrap();
let string = "
80,01,00
80,00
01
00,80,01,02
The not allowed values are as below:
80,
,01,
,00
8
800
80, --> with comma in the end.
,01, --> comma at the start and end.
,00 --> comma at the start.
8 --> with only one digit
800 --> with three digits
I have tried the below regex pattern:
^(*([0-9][0-9][,])+([0-9][0-9])*([,][0-9][0-9]))$";
// 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);
}
}
