Trait Implementations

impl Clone for Xform

fn clone(&self) -> Xform

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Xform

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

Formats the value using the given formatter.

impl Default for Xform

Implement Default for Xform to return identity matrix

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Xform

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Xform

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

Formats the value using the given formatter.

impl Index<(usize, usize)> for Xform

type Output = f32

The returned type after indexing.

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

Performs the indexing (container[index]) operation.

impl IndexMut<(usize, usize)> for Xform

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

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

impl Mul for &Xform

type Output = Xform

The resulting type after applying the * operator.

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

Performs the * operation.

impl Mul for Xform

type Output = Xform

The resulting type after applying the * operator.

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

Performs the * operation.

impl MulAssign for Xform

fn mul_assign(&mut self, rhs: Self)

impl PartialEq for Xform

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

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
