Struct Borrowing 

pub struct Borrowing<C, Lb: ?Sized, Rb: ?Sized = Lb>(/* private fields */)
where
    C: Compare<Lb, Rb>;

A comparator that borrows its parameters before comparing them.

See Compare::borrow for an example.

Trait Implementations

impl<C, Lb: ?Sized, Rb: ?Sized> Clone for Borrowing<C, Lb, Rb>

where C: Compare<Lb, Rb> + Clone,

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<C, L, R, Lb: ?Sized, Rb: ?Sized> Compare<L, R> for Borrowing<C, Lb, Rb>

where C: Compare<Lb, Rb>, L: Borrow<Lb> + ?Sized, R: Borrow<Rb> + ?Sized,

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

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.
