Trait RelativeEq

pub trait RelativeEq<Rhs = Self>: AbsDiffEq<Rhs>
where
    Rhs: ?Sized,
{
    // Required methods
    fn default_max_relative() -> Self::Epsilon;
    fn relative_eq(
        &self,
        other: &Rhs,
        epsilon: Self::Epsilon,
        max_relative: Self::Epsilon,
    ) -> bool;

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

The inverse of RelativeEq::relative_eq.

Object Safety

This trait is not object safe.
