Struct compare::Natural
[−]
[src]
pub struct Natural<T: Ord + ?Sized>(_);
A comparator that delegates to Ord
.
Examples
use compare::{Compare, natural}; use std::cmp::Ordering::{Less, Equal, Greater}; let a = &1; let b = &2; let cmp = natural(); assert_eq!(cmp.compare(a, b), Less); assert_eq!(cmp.compare(b, a), Greater); assert_eq!(cmp.compare(a, a), Equal);
Trait Implementations
impl<T: Ord + ?Sized> Compare<T> for Natural<T>
[src]
fn compare(&self, l: &T, r: &T) -> Ordering
Compares two values, returning Less
, Equal
, or Greater
if l
is less than, equal to, or greater than r
, respectively. Read more
fn compares_lt(&self, l: &T, r: &T) -> bool
Checks if l
is less than r
.
fn compares_le(&self, l: &T, r: &T) -> bool
Checks if l
is less than or equal to r
.
fn compares_ge(&self, l: &T, r: &T) -> bool
Checks if l
is greater than or equal to r
.
fn compares_gt(&self, l: &T, r: &T) -> bool
Checks if l
is greater than r
.
fn compares_eq(&self, l: &T, r: &T) -> bool
Checks if l
is equal to r
.
fn compares_ne(&self, l: &T, r: &T) -> bool
Checks if l
is not equal to r
.
fn borrowing(self) -> Borrowing<Self, L, R> where
Self: Sized,
Self: Sized,
Borrows the comparator's parameters before comparing them. Read more
fn rev(self) -> Rev<Self> where
Self: Sized,
Self: Sized,
