Trait LeastElement 

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

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

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

Required Methods

fn least() -> Self

Returns the unique least element.

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

Provided Methods

fn is_least(&self) -> bool

Returns true if and only if self is the least 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.
