Trait Ulps

pub trait Ulps {
    type U: Copy;

    // Required methods
    fn ulps(&self, other: &Self) -> <Self as Ulps>::U;
    fn next(&self) -> Self;
    fn prev(&self) -> Self;
}

Required Associated Types

type U: Copy

Required Methods

fn ulps(&self, other: &Self) -> <Self as Ulps>::U

The number of representable values or ULPs (Units of Least Precision) that separate self and other. The result U is an integral value, and will be zero if self and other are exactly equal.

fn next(&self) -> Self

The next representable number above this one

fn prev(&self) -> Self

The previous representable number below this one

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.
