Convert to Point (ignoring z and w).

pub fn dot(self, other: Self) -> f32

Dot product.

Trait Implementations

impl Clone for Vec4

fn clone(&self) -> Vec4

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Vec4

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Vec4

fn default() -> Self

Returns the “default value” for a type.

impl From<Point> for Vec4

fn from(p: Point) -> Self

Converts to this type from the input type.

impl From<Vec4> for Point

fn from(v: Vec4) -> Self

Converts to this type from the input type.

impl Mul<Vec4> for Mat4

type Output = Vec4

The resulting type after applying the * operator.

fn mul(self, rhs: Vec4) -> Vec4

Performs the * operation.

impl PartialEq for Vec4

fn eq(&self, other: &Vec4) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
