pub enum MinMaxResult<T> {
    NoElements,
    OneElement(T),
    MinMax(T, T),
}
Expand description

MinMaxResult is an enum returned by minmax. See Itertools::minmax() for more detail.

Variants§

§

NoElements

Empty iterator

§

OneElement(T)

Iterator with one element, so the minimum and maximum are the same

§

MinMax(T, T)

More than one element in the iterator, the first element is not larger than the second

Implementations§

source§

impl<T: Clone> MinMaxResult<T>

source

pub fn into_option(self) -> Option<(T, T)>

into_option creates an Option of type (T, T). The returned Option has variant None if and only if the MinMaxResult has variant NoElements. Otherwise Some((x, y)) is returned where x <= y. If the MinMaxResult has variant OneElement(x), performing this operation will make one clone of x.

§Examples
use itertools::MinMaxResult::{self, NoElements, OneElement, MinMax};

let r: MinMaxResult<i32> = NoElements;
assert_eq!(r.into_option(), None);

let r = OneElement(1);
assert_eq!(r.into_option(), Some((1, 1)));

let r = MinMax(1, 2);
assert_eq!(r.into_option(), Some((1, 2)));
