Zero allocation big integer library for no_std Rust, borrowing heavily in terms of code and algorithms from num-bigint.
Honestly, you're probably much better off using num-bigint. Only use this library if you absolutely need to be zero allocation because it just doesn't have the same breadth of functionality nor the extensive testing of num-bigint.
Quite the pep talk, I know.
