Struct compare::Borrow

pub struct Borrow<C, Lb: ?Sized, Rb: ?Sized = Lb>(_, _) where C: Compare<Lb, Rb>;

A comparator that borrows its parameters before comparing them.

See Compare::borrow for an example.

Trait Implementations

impl<C, Lhs: ?Sized, Rhs: ?Sized, Lb: ?Sized, Rb: ?Sized> Compare<Lhs, Rhs> for Borrow<C, Lb, Rb> where C: Compare<Lb, Rb>, Lhs: StdBorrow<Lb>, Rhs: StdBorrow<Rb>

fn compare(&self, lhs: &Lhs, rhs: &Rhs) -> Ordering

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

fn compares_lt(&self, lhs: &Lhs, rhs: &Rhs) -> bool

Checks if lhs is less than rhs.

fn compares_le(&self, lhs: &Lhs, rhs: &Rhs) -> bool

Checks if lhs is less than or equal to rhs.

fn compares_ge(&self, lhs: &Lhs, rhs: &Rhs) -> bool

Checks if lhs is greater than or equal to rhs.

fn compares_gt(&self, lhs: &Lhs, rhs: &Rhs) -> bool

Checks if lhs is greater than rhs.

fn compares_eq(&self, lhs: &Lhs, rhs: &Rhs) -> bool

Checks if lhs is equal to rhs.

fn compares_ne(&self, lhs: &Lhs, rhs: &Rhs) -> bool

Checks if lhs is not equal to rhs.

fn borrow(self) -> Borrow<Self, Lhs, Rhs> 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<Lhs, Rhs>, Self: Sized

Lexicographically combines the comparator with another.

impl<C, Lb: ?Sized, Rb: ?Sized> Clone for Borrow<C, Lb, Rb> where C: Compare<Lb, Rb> + Clone

fn clone(&self) -> Borrow<C, Lb, Rb>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<C, Lb: ?Sized, Rb: ?Sized> Copy for Borrow<C, Lb, Rb> where C: Compare<Lb, Rb> + Copy

impl<C, Lb: ?Sized, Rb: ?Sized> Default for Borrow<C, Lb, Rb> where C: Compare<Lb, Rb> + Default

fn default() -> Borrow<C, Lb, Rb>

Returns the "default value" for a type.

impl<C, Lb: ?Sized, Rb: ?Sized> PartialEq for Borrow<C, Lb, Rb> where C: Compare<Lb, Rb> + PartialEq

fn eq(&self, other: &Borrow<C, Lb, Rb>) -> bool

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

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

This method tests for !=.

impl<C, Lb: ?Sized, Rb: ?Sized> Eq for Borrow<C, Lb, Rb> where C: Compare<Lb, Rb> + Eq

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

Formats the value using the given formatter.
