Trait Implementations

impl<F, T> Clone for Transform2<F, T>

fn clone(&self) -> Self

fn default() -> Self

Returns the “default value” for a type.

impl<T: Space, F: Space> From<Transform2<T, F>> for Affine

fn from(value: Transform2<T, F>) -> Self

Converts to this type from the input type.

impl HelperFunctions for Transform2
