Deprecated since 1.3.0

: has not proven itself

MinMaxResult is an enum returned by min_max. See Iterator::min_max for more detail.

Variants

NoElements
Deprecated since 1.3.0

: has not proven itself

Empty iterator

OneElement
Deprecated since 1.3.0

: has not proven itself

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

MinMax
Deprecated since 1.3.0

: has not proven itself

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

Methods

impl<T> MinMaxResult<T> where T: Clone

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

Deprecated since 1.3.0

: has not proven itself

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 variant Some(x,y) is returned where x <= y. If MinMaxResult has variant OneElement(x), performing this operation will make one clone of x.

Examples

#![feature(iter_min_max)] fn main() { use std::iter::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))); }
#![feature(iter_min_max)]

use std::iter::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)));
