[][src]Enum itertools::MinMaxResult

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

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

Variants

Empty iterator

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

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

Methods

impl<T: Clone> MinMaxResult<T>
[src]

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)));
