# Enum itertools::MinMaxResult

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

`MinMaxResult` is an enum returned by `minmax`.

See `.minmax()` for more detail.

## Variants§

§

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)));``````
