type Epsilon = E

Used for specifying relative comparisons.

fn default_epsilon() -> E

The default tolerance to use when testing values that are close together.

fn abs_diff_eq(&self, other: &Self, epsilon: E) -> bool

A test for equality that uses the absolute difference to compute the approximate equality of two numbers.

fn abs_diff_ne(&self, other: &Rhs, epsilon: Self::Epsilon) -> bool

The inverse of AbsDiffEq::abs_diff_eq.

impl<V: Clone + VectorSpace, R: Clone> Clone for Decomposed<V, R>where V::Scalar: Clone,

fn clone(&self) -> Decomposed<V, R>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)
