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 copy 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

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.

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

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

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

Formats the value using the given formatter.

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

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

fn default() -> Self

Returns the “default value” for a type.

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

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

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

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

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

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

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