Crate primeval

Primeval-rs

A monstrosity of a prime number generator. (It's dead simple)

Features

• ZERO Dependencies (will always be this way)
• CLI Interface
• Rust library (see crates.io)

Usage

CLI

• primeval help: displays a help menu.
• primeval gen <limit>: generates all the prime numbers up to a limit
• primeval prime <number>: determines whether a number is prime or not
• primeval version: shows version info

Rust Crate

main.rs

extern crate primeval;

fn main(){
  // Primality?
  let result = primeval::is_prime(2);

  // Generation, in this case all the primes from 0 - 1000
  let result: Vec<usize> = primeval::primes_gen(1000).collect::<Vec<_>>();
}

Installation (CLI)

1. git clone https://github.com/ajmwagar/primeval-rs
2. cd primeval-rs
3. cargo build --release
4. cd target/release
5. ./primeval help
6. Profit!

You can also move the binary into /usr/bin or somewhere else in your PATH to use from anywhere.

Tests & Benchmarks

• To run the test suite: cargo test
• Always looking for more! (Submit a pull request)
• To benchmark Primeval: cargo bench
• Benchmarks prime number generation up to 1000000

Roadmap

• [x] Rust Module/API
• [ ] Cleaner UI/CLI
• [ ] More SPEED!
• [ ] Factorization
• [ ] Larger number support
• [ ] Heat death of the universe

Functions

is_prime	Returns whether a given number is prime
primes_gen	Generate primes up to a given limit using the Seive of Eratorthenes Use Sieve_of_Eratosthenes for prime generation (https://en.wikipedia.org/wiki/Sieve_of_Eratosthenes)
