Equality that is defined using the absolute difference of two numbers.

Associated Types

Required methods

`fn default_epsilon() -> Self::Epsilon`[src]

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`[src]

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`[src]

The inverse of ApproxEq::abs_diff_eq.
