min-max: max! and min! macros for Rust

[dependencies]
min-max = "0.1"

Usage

use min_max::*;

fn main() {
    let max = max!(1, 5, 7, 2, 4, 9, 3);
    assert_eq!(max, 9);
    let min = min!(1, 5, 7, 2, 4, 9, 3);
    assert_eq!(min, 1);
}

Does it work on floats?

Yep. But you need to use max_partial!/min_partial!

use min_max::*;

fn main() {
    let partial_max = max_partial!(1.8f64, 5.8, 7.8, 2.8, 4.8, 9.8, 3.8);
    assert!((9.8 - partial_max).abs() < 1e-5);
    let partial_min = min_partial!(1.8f64, 5.8, 7.8, 2.8, 4.8, 9.8, 3.8);
    assert!((1.8 - partial_min).abs() < 1e-5);
}

What about NaN?

Do not use when your data contains NaN. When NaN is at the end, NaN is returned. Otherwise, the min/max excluding NaN is returned.

use min_max::*;

fn main() {
    let partial_max = max_partial!(1.8, 5.8, f64::NAN, 2.8, 4.8, 9.8, 3.8);
    assert!((9.8 - partial_max).abs() < 1e-5);
    let partial_max = max_partial!(1.8, 5.8, 2.8, 4.8, 9.8, 3.8, f64::NAN);
    assert!(partial_max.is_nan());
    let partial_min = min_partial!(1.8, 5.8, f64::NAN, 2.8, 4.8, 9.8, 3.8);
    assert!((1.8 - partial_min).abs() < 1e-5);
    let partial_min = max_partial!(1.8, 5.8, 2.8, 4.8, 9.8, 3.8, f64::NAN);
    assert!(partial_min.is_nan());
}
