A 4x4 Matrix with elements arraged in row-major order.

A Mat4 is laid out as follows:

    [ a  b  c  d ]
A = [ e  f  g  h ]
    [ i  j  k  l ]
    [ m  n  o  p ]

Trait Implementations

impl Clone for Mat4

fn clone(&self) -> Mat4

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Mat4

impl Debug for Mat4

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

Formats the value using the given formatter.

impl Default for Mat4

fn default() -> Mat4

Returns the "default value" for a type.

impl PartialEq for Mat4

fn eq(&self, other: &Mat4) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Mat4) -> bool

This method tests for !=.

impl Mul<Mat4> for Mat4

type Output = Mat4

The resulting type after applying the * operator.

fn mul(self, mat4: Mat4) -> Mat4

Multiplies two Mat4s together, returning a new Mat4.

Keep in mind that matrix multiplication is not commutative, such that A*B != B*A for most matrices (the main exception being the Identity matrix)

Example:

let some_mat4 = mat4 * some_other_mat4;

impl Mul<Vec4> for Mat4

type Output = Vec4

The resulting type after applying the * operator.

fn mul(self, vec4: Vec4) -> Vec4

Performs the * operation.

impl Mul<Mat4> for f32

type Output = Mat4

The resulting type after applying the * operator.

fn mul(self, mat4: Mat4) -> Mat4

Performs the * operation.
