[−][src]Struct approx::AbsDiff

pub struct AbsDiff<T: AbsDiffEq + ?Sized> {
    pub epsilon: T::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: T::Epsilon

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

Methods

impl<T: ?Sized> AbsDiff<T> where
    T: AbsDiffEq, [src]

pub fn epsilon(self, epsilon: T::Epsilon) -> AbsDiff<T>[src]

Replace the epsilon value with the one specified.

pub fn eq(self, lhs: &T, rhs: &T) -> bool[src]

Peform the equality comparison

pub fn ne(self, lhs: &T, rhs: &T) -> bool[src]

Peform the inequality comparison
