// Meant for parsing the output of P2Pool and finding payouts and total XMR found.
// Why Regex instead of the standard library?
// 1. I'm already using Regex
// 2. It's insanely faster
//
// The following STDLIB implementation takes [0.003~] seconds to find all matches given a [String] with 30k lines:
// let mut n = 0;
// for line in P2POOL_OUTPUT.lines() {
// if line.contains("payout of [0-9].[0-9]+ XMR") { n += 1; }
// }
//
// This regex function takes [0.0003~] seconds (10x faster):
// let regex = Regex::new("payout of [0-9].[0-9]+ XMR").unwrap();
// let n = regex.find_iter(P2POOL_OUTPUT).count();
//
// Both are nominally fast enough where it doesn't matter too much but meh, why not use regex.
