Struct rin::math::AbsDiff[][src]

pub struct AbsDiff<A, B = A> where
    B: ?Sized,
    A: AbsDiffEq<B> + ?Sized
{ pub epsilon: <A as AbsDiffEq<B>>::Epsilon, }

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

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

Example

use std::f64;
use approx::AbsDiff;

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

Fields

epsilon: <A as AbsDiffEq<B>>::Epsilon

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

Implementations
