See comparing.

Trait Implementations

impl<S: Clone + ?Sized, T: Clone + ?Sized + Ord, F: Clone + Fn(&S) -> T> Clone for Comparing<S, T, F>

fn clone(&self) -> Comparing<S, T, F>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<S, T, F> Comparator<S> for Comparing<S, T, F>

where S: ?Sized, T: Ord, F: Fn(&S) -> T,

fn cmp(&self, left: &S, right: &S) -> Ordering

This method returns an Ordering between left and right.

fn reversed(self) -> ReversedOrder<T, Self>

where Self: Sized,

This method returns a Comparator which is semantically reversed from self.

fn then<N>(self, next: N) -> CompareThen<T, Self, N>

where Self: Sized, N: Comparator<T>,

This method returns a Comparator which is further refining the semantics of self.

fn max<'a>(&self, left: &'a T, right: &'a T) -> &'a T

This function returns the greater instace (out of left and right) according to cmp.

fn min<'a>(&self, left: &'a T, right: &'a T) -> &'a T

This function returns the less instace (out of left and right) according to cmp.

impl<S: Debug + ?Sized, T: Debug + ?Sized + Ord, F: Debug + Fn(&S) -> T> Debug for Comparing<S, T, F>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<S: Copy + ?Sized, T: Copy + ?Sized + Ord, F: Copy + Fn(&S) -> T> Copy for Comparing<S, T, F>
