Struct KeyValueComparer 

pub struct KeyValueComparer<T, K> { /* private fields */ }

Compares the pairs of a key and an item of a sorted cache (KeyValueComparer<TObject, TKey>): by the items with the comparer when there is one, then by the keys, so that each pair has a unique position.

Implementations

impl<T, K> KeyValueComparer<T, K>

pub fn new(comparer: Option<Rc<dyn Fn(&T, &T) -> Ordering>>) -> Self

A comparer of pairs by comparer, then by the keys (KeyValueComparer(IComparer<TObject>?)).

pub fn item_comparer(&self) -> Option<&Rc<dyn Fn(&T, &T) -> Ordering>>

The comparer of the items.

impl<T: 'static, K: Hash + 'static> KeyValueComparer<T, K>

pub fn compare(&self, x: &(K, T), y: &(K, T)) -> Ordering

Compares two pairs (Compare).

pub fn to_fn(&self) -> Rc<dyn Fn(&(K, T), &(K, T)) -> Ordering>

The comparer as a function.
