}Expand description
Equality that is defined using the absolute difference of two numbers.
Required Associated Types
Required Methods
fn default_epsilon() -> Self::Epsilon
fn default_epsilon() -> Self::Epsilon
The default tolerance to use when testing values that are close together.
This is used when no epsilon value is supplied to the [abs_diff_eq!], [relative_eq!],
or [ulps_eq!] macros.
fn abs_diff_eq(&self, other: &Rhs, epsilon: Self::Epsilon) -> bool
fn abs_diff_eq(&self, other: &Rhs, epsilon: Self::Epsilon) -> bool
A test for equality that uses the absolute difference to compute the approximate equality of two numbers.
Provided Methods
fn abs_diff_ne(&self, other: &Rhs, epsilon: Self::Epsilon) -> bool
fn abs_diff_ne(&self, other: &Rhs, epsilon: Self::Epsilon) -> bool
The inverse of AbsDiffEq::abs_diff_eq.
