Trait Implementations§

impl Clone for Transform

source§

fn clone(&self) -> Transform

Returns a copy of the value. Read more
1.0.0 · source§

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

Performs copy-assignment from source. Read more
source§

impl Debug for Transform

source§

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

Formats the value using the given formatter. Read more
source§

impl Default for Transform

source§

fn default() -> Transform

Returns the “default value” for a type. Read more
source§

impl From<Matrix> for Transform

source§

fn from(m: Matrix) -> Self

Converts to this type from the input type.
source§

impl PartialEq for Transform

source§

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
source§

impl TryFrom<Transform> for ValidTransform

source§

fn try_from(t: Transform) -> Result<ValidTransform, InvalidTransform>

Validates a Transform before converting it to a ValidTransform.

A transform is valid if it is invertible. For example, a matrix with all-zeros is not invertible, and it is invalid.

§

type Error = InvalidTransform

The type returned in the event of a conversion error.
