A totally-ordered distance metric value.

Required Methods

fn next_up(&self) -> Self

fn zero() -> Self

fn max_value() -> Self

fn min_value() -> Self

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.
