Trait approx::RelativeEq

pub trait RelativeEq: AbsDiffEq {
    fn default_max_relative() -> Self::Epsilon;
    fn relative_eq(
        &self,
        other: &Self,
        epsilon: Self::Epsilon,
        max_relative: Self::Epsilon
    ) -> bool;

    fn relative_ne(
        &self,
        other: &Self,
        epsilon: Self::Epsilon,
        max_relative: Self::Epsilon
    ) -> bool { ... }
}

Equality comparisons between two numbers using both the absolute difference and relative based comparisons.

Required Methods

fn default_max_relative() -> Self::Epsilon

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

This is used when no max_relative value is supplied to the relative_eq macro.

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

A test for equality that uses a relative comparison if the values are far apart.

Provided Methods

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

The inverse of ApproxEq::relative_eq.
