Struct rin::math::Relative [−][src]
pub struct Relative<A, B = A> where
B: ?Sized,
A: RelativeEq<B> + ?Sized, { pub epsilon: <A as AbsDiffEq<B>>::Epsilon, pub max_relative: <A as AbsDiffEq<B>>::Epsilon, }
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 as AbsDiffEq<B>>::Epsilon
The tolerance to use when testing values that are close together.
max_relative: <A as AbsDiffEq<B>>::Epsilon
The relative tolerance for testing values that are far-apart.
