Trait Compare 

pub trait Compare<L: ?Sized, R: ?Sized = L> {
    // Required method
    fn compare(&self, l: &L, r: &R) -> Ordering;

    // Provided methods
    fn compares_lt(&self, l: &L, r: &R) -> bool { ... }
    fn compares_le(&self, l: &L, r: &R) -> bool { ... }
    fn compares_ge(&self, l: &L, r: &R) -> bool { ... }
    fn compares_gt(&self, l: &L, r: &R) -> bool { ... }
    fn compares_eq(&self, l: &L, r: &R) -> bool { ... }
    fn compares_ne(&self, l: &L, r: &R) -> bool { ... }
}

A comparator imposing a total order.

The compare method accepts two values (which may be of the same type or different types) and returns an ordering on them.

Comparators are useful for parameterizing the behavior of sort methods and certain data structures like binary heaps.

Required Methods

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.

Provided Methods

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.
