Trait GreatestElement 

pub trait GreatestElement: PartialOrd + Sized {
    // Required method
    fn greatest() -> Self;

    // Provided method
    fn is_greatest(&self) -> bool { ... }
}

A partial order with a greatest element (which is necessarily unique).

Required Methods

fn greatest() -> Self

Returns the unique greatest element.

For all values other of type Self, Self::greatest() >= other must be true.

Provided Methods

fn is_greatest(&self) -> bool

Returns true if and only if self is the greatest element.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
