Trait Maximum

pub trait Maximum: Ord {
    const MAX: Self;
}

Trait for types for which a maximum possible value exists.

This exists primarily to play nicely with std::cmp::Reverse keys for achieving high performance reverse iteration.

Required Associated Constants

const MAX: Self

The returned value must be greater than or equal to all possible values for this type.

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.
