pub struct KeyComparator<F> { /* private fields */ }

Trait Implementations

impl<S, F, O> Compare<HeadTail<S>> for KeyComparator<F>

where S: Stream, F: Fn(&S::Item) -> O, O: Ord,

fn compare(&self, l: &HeadTail<S>, r: &HeadTail<S>) -> 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>

where Self: Sized,

Borrows the comparator’s parameters before comparing them.

fn rev(self) -> Rev<Self>

where Self: Sized,

Reverses the ordering of the comparator.

fn swap(self) -> Swap<Self>

where Self: Sized,

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

fn then<D>(self, then: D) -> Then<Self, D>

where D: Compare<L, R>, Self: Sized,

Lexicographically combines the comparator with another.
