Equality that is defined using the absolute difference of two numbers.

Associated Types

type Epsilon

Used for specifying relative comparisons.

Required methods

fn default_epsilon() -> Self::Epsilon

The default tolerance to use when testing values that are close together.

This is used when no epsilon value is supplied to the abs_diff_eq!, relative_eq!, or ulps_eq! macros.

fn abs_diff_eq(&self, other: &Self, epsilon: Self::Epsilon) -> bool

A test for equality that uses the absolute difference to compute the approximate equality of two numbers.

Provided methods

fn abs_diff_ne(&self, other: &Self, epsilon: Self::Epsilon) -> bool

The inverse of ApproxEq::abs_diff_eq.
