Currently, it seems that rustgpu does not support operator overloading (there is no ops module under spirv_std, and none of the examples seem to do this).

This is useful because although linear algebra is the most popular mathematical representation for transformations in computer graphics, it is not the only option.

For example, I currently use projective geometric algebra for skin animations. To do this I need to define a multivector type on the shader that is capable of addition, multiplication, scalar multiplication...

Of course, one can work around the issue by defining methods, but this is less ergonomic than having operators.

まず spirv_std 領域を調査し、特に報告されている ops モジュールの欠如を確認して、演算子の使用方法に関する既存の例と比較してください。カスタム shader 型で、メソッドベースの回避策を必要とせず、加算、乗算、スカラー乗算などの演算子を使用できるようになれば完了です。
