Trait Implementations

impl Class<PxTransform> for PxTransform

fn as_ptr(&self) -> *const PxTransform

Returns a raw const pointer to the wrapped type. Retrieving a raw pointer is safe. However, pretty much any use of a raw pointer is unsafe. In particular: this pointer should not be used to construct a second owning wrapper around the pointer.

fn as_mut_ptr(&mut self) -> *mut PxTransform

Returns a raw mut pointer to the wrapped type. Retrieving a raw pointer is safe. However, pretty much any use of a raw pointer is unsafe. In particular: this pointer should not be used to construct a second owning wrapper around the pointer.

impl Clone for PxTransform

fn clone(&self) -> PxTransform

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for PxTransform

fn default() -> Self

Returns the “default value” for a type.

impl From<PxTransform> for PxTransform

fn from(value: PxTransform) -> Self

Converts to this type from the input type.

impl From<PxTransform> for PxTransform

fn from(transform: PxTransform) -> Self

Converts to this type from the input type.

impl Copy for PxTransform

impl Send for PxTransform

impl Sync for PxTransform
