[−][src]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 limitprimeval prime <number>
: determines whether a number is prime or notprimeval version
: shows version info
Rust Crate
main.rs
extern crate primeval; // We use usize to make sure nothing breaks when cross compiling. 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)
git clone https://github.com/ajmwagar/primeval-rs
cd primeval-rs
cargo build --release
cd target/release
./primeval help
- 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) |
