}Expand description
Equality that is defined using the absolute difference of two numbers.
Required Associated Types§
Required Methods§
sourcefn 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.
sourcefn 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§
sourcefn abs_diff_ne(&self, other: &Rhs, epsilon: Self::Epsilon) -> bool
fn abs_diff_ne(&self, other: &Rhs, epsilon: Self::Epsilon) -> bool
The inverse of ApproxEq::abs_diff_eq.
Object Safety§
This trait is not object safe.
