Struct rsvg::transform::ValidTransform

pub struct ValidTransform(Transform);

A transform that has been checked to be invertible.

We need to validate user-supplied transforms before setting them on Cairo, so we use this type for that.

Trait Implementations

impl Clone for ValidTransform

fn clone(&self) -> ValidTransform

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ValidTransform

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

Formats the value using the given formatter.

impl Deref for ValidTransform

type Target = Transform

The resulting type after dereferencing.

fn deref(&self) -> &Transform

Dereferences the value.

impl From<ValidTransform> for Matrix

fn from(t: ValidTransform) -> Matrix

Converts to this type from the input type.

impl PartialEq for ValidTransform

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

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

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.

impl TryFrom<Transform> for ValidTransform

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.
