The midpoint is the average of, or halfway point between, two vectors. a.midpoint(b) should yield the same result as a.lerp(b, 0.5) while being slightly cheaper to compute.

pub fn abs_diff_eq(self, rhs: Vec4, max_abs_diff: f32) -> bool

Returns true if the absolute difference of all elements between self and rhs is less than or equal to max_abs_diff.

This can be used to compare if two vectors contain similar elements. It works best when comparing with a known value. The max_abs_diff that should be used used depends on the values being compared against.

For more see comparing floating point numbers.

pub fn mul_add(self, a: Vec4, b: Vec4) -> Vec4

Using mul_add may be more performant than an unfused multiply-add if the target architecture has a dedicated fma CPU instruction. However, this is not always true, and will be heavily dependant on designing algorithms with specific target hardware in mind.

impl VectorSpace for Vec4

const ZERO: Self = Vec4::ZERO

The zero vector, which is the identity of addition for the vector space type.

fn lerp(&self, rhs: Self, t: f32) -> Self

Perform vector space linear interpolation between this element and another, based on the parameter t. When t is 0, self is recovered. When t is 1, rhs is recovered.

impl Zeroable for Vec4

fn zeroed() -> Self

Calls zeroed.
