Trait Implementations

impl Clone for Mat4

fn clone(&self) -> Mat4

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Mat4

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

Formats the value using the given formatter.

impl Default for Mat4

fn default() -> Self

Returns the “default value” for a type.

impl Index<usize> for Mat4

type Output = Vec4

The returned type after indexing.

fn index(&self, index: usize) -> &Self::Output

Performs the indexing (container[index]) operation.

impl IndexMut<usize> for Mat4

fn index_mut(&mut self, index: usize) -> &mut Self::Output

Performs the mutable indexing (container[index]) operation.

impl Mul<Vec3> for Mat4

type Output = Vec3

The resulting type after applying the * operator.

fn mul(self, rhs: Vec3) -> Self::Output

Performs the * operation.

impl Mul<Vec4> for Mat4

type Output = Vec4

The resulting type after applying the * operator.

impl PartialEq for Mat4

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