Enum itertools::MinMaxResult
source · [−]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
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
sourceimpl<T: Clone> MinMaxResult<T>
impl<T: Clone> MinMaxResult<T>
sourcepub fn into_option(self) -> Option<(T, T)>
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)));Trait Implementations
