Trait Implementations

impl<F: Clone> Clone for FnComparator<F>

fn clone(&self) -> FnComparator<F>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T, F> Compare<T, T> for FnComparator<F> where
    F: Fn(&T, &T) -> Ordering, 

fn compare(&self, a: &T, b: &T) -> Ordering

Compares two values, returning Less, Equal, or Greater if l is less than, equal to, or greater than r, respectively.

fn compares_lt(&self, l: &L, r: &R) -> bool

Checks if l is less than r.

fn compares_le(&self, l: &L, r: &R) -> bool

Checks if l is less than or equal to r.

fn compares_ge(&self, l: &L, r: &R) -> bool

Checks if l is greater than or equal to r.

fn compares_gt(&self, l: &L, r: &R) -> bool

Checks if l is greater than r.

fn compares_eq(&self, l: &L, r: &R) -> bool

Checks if l is equal to r.

fn compares_ne(&self, l: &L, r: &R) -> bool

Checks if l is not equal to r.

fn borrowing(self) -> Borrowing<Self, L, R>

Borrows the comparator's parameters before comparing them.

fn rev(self) -> Rev<Self>

Reverses the ordering of the comparator.

fn swap(self) -> Swap<Self>

Swaps the comparator's parameters, maintaining the underlying ordering.

fn then<D>(self, then: D) -> Then<Self, D> where
    D: Compare<L, R>, 

Lexicographically combines the comparator with another.

impl<F: Copy> Copy for FnComparator<F>

impl<F: Debug> Debug for FnComparator<F>

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

Formats the value using the given formatter.

impl<F: Default> Default for FnComparator<F>

fn default() -> FnComparator<F>

Returns the "default value" for a type.

impl<F: Eq> Eq for FnComparator<F>

impl<F: PartialEq> PartialEq<FnComparator<F>> for FnComparator<F>

fn eq(&self, other: &FnComparator<F>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &FnComparator<F>) -> bool

This method tests for !=.
