Function max 

pub fn max<T: Ord>(v1: T, v2: T) -> T

This item is validated for IEC 61508 (SIL 2) and ISO 26262 (ASIL B).

Compares and returns the maximum of two values.

Returns the second argument if the comparison determines them to be equal.

Internally uses an alias to Ord::max.

Examples

use std::cmp;

assert_eq!(cmp::max(1, 2), 2);
assert_eq!(cmp::max(2, 2), 2);

use std::cmp::{self, Ordering};

#[derive(Eq)]
struct Equal(&'static str);

impl PartialEq for Equal {
    fn eq(&self, other: &Self) -> bool { true }
}
impl PartialOrd for Equal {
    fn partial_cmp(&self, other: &Self) -> Option<Ordering> { Some(Ordering::Equal) }
}
impl Ord for Equal {
    fn cmp(&self, other: &Self) -> Ordering { Ordering::Equal }
}

assert_eq!(cmp::max(Equal("v1"), Equal("v2")).0, "v2");
