pub struct Relative<A, B = A> where
    A: RelativeEq<B> + ?Sized,
    B: ?Sized
{ pub epsilon: A::Epsilon, pub max_relative: A::Epsilon, }
Expand description

The requisite parameters for testing for approximate equality using a relative based comparison.

This is not normally used directly, rather via the assert_relative_{eq|ne}! and relative_{eq|ne}! macros.

Example

use std::f64;
use approx::Relative;

Relative::default().eq(&1.0, &1.0);
Relative::default().epsilon(f64::EPSILON).eq(&1.0, &1.0);
Relative::default().max_relative(1.0).eq(&1.0, &1.0);
Relative::default().epsilon(f64::EPSILON).max_relative(1.0).eq(&1.0, &1.0);
Relative::default().max_relative(1.0).epsilon(f64::EPSILON).eq(&1.0, &1.0);

Fields

epsilon: A::Epsilon

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

max_relative: A::Epsilon

The relative tolerance for testing values that are far-apart.
