kindness

Methods for choosng random elements from an iterator.

Includes choose_item(), choose_max(), choose_max_by(), choose_max_by_key(), choose_min(), choose_min_by(), choose_min_by_key()

Does not allocate or iterate iterators more than once.
If you are confused by the name of the crate, think "random max of".

This crate works with Cargo with a Cargo.toml like:

[dependencies]
kindness = "0.2.0"
rand = "0.8.5"

Getting started

use kindness::*;
use rand::SeedableRng;

fn main() {    
    let mut rng = rand::rngs::StdRng::seed_from_u64(123);
    let m =[3,2,1,2,3].iter().choose_max(&mut rng).unwrap();
    assert_eq!(*m, 3)
}
