Yes, theoretically you could do it, but I am not sure if it is currently supported in Rust-Gpu.

| I like the general idea but if rust-gpu doesn't use it internally I'm not really seeing why it should add these things, rather than putting them in a separate crate for people to use? |

| @oisyn Yea the thing is, my plan is to add support for subgroup operations after this PR has been merged, and there are some ops like |

| Right! I would suggest adding this trait as part of that work. |

It would be nicer to make this one per line, like i32: IVec2 => 2, IVec3 => 3, IVec4 => 4;
Also, you can make the macro implement both Vector and ScalarOrVector at the same time.

This PR adds the
ScalarOrVector<S>trait which represents types that can be either a scalar or a vector!Motivation:
I am currently adding support for subgroup operations, and for example
OpGroupNonUniformIAdds result type must be scalar or vector of integer type, so it would be useful to have this trait.
