prime-iter
growingv0.1.0
An incremental-sieve based prime generator
46
fast-factor
experimentalv0.1.4
Fast functions for factoring unsigned integers
38
concurrent_prime_sieve
growingv0.3.3
Tools for generating filters and collections with primes concurrently. Rust implementation of the Sieve of Atkin. This implementation runs in O( sqrt(max_num) + section_size ) (where section_size = max_num - min_num). Integrated with primal for increased speed in some cases.
