A short bit of code to create every possible string combination of given length, with a given charset. The program outputs the combinations to `stdout` and periodic statistics to `stderr`.
This project uses quite a bit of `unsafe` blocks to acheive the equivilent of java's `public static` in the form of `static mut`. I know some people don't like unsafe rust code, if you are one of those people... too bad.
Since this code is just single-threaded I can only get about 5M permutations a second when not IO limited. (Tested by redirecting `stduout` to `/dev/null`). Later on I might make this multi-threaded to speed up the calculation speed.
