Random number generators with a fixed number of set bits (ones).
Setup
To use this crate, add the following entry to your Cargo.toml
file in the dependencies
section:

subcommand:
cargo add randbits
Usage
use rand::thread_rng;
use rand_bits::RngBits;
let mut rng = thread_rng();
let x: u8 = rng.gen_bits(4); // generates a u8 with 4 set bits
assert_eq!(x.count_ones(), 4);
let y: u16 = rng.gen_bits(15); // generates a u16 with 15 set bits
assert_eq!(y.count_ones(), 15);
let z: u64 = rng.gen_bits(1); // generates a u64 with 1 set bits
assert_eq!(z.count_ones(), 1);
