Is it possible to create a struct with given name and its attribute name with types. In my application,
in each example I create different structs as needed for the physics. Each struct may differ by
some attributes. And these are operated by a macro. So macro will work on its attributes.
To summarize, Can I have some thing like
let rigd_fluid = get_particle_array!(name="rigidbody", x=x, y=y, z=z, m=m, pressure=p, rho=rho)
Or create the struct attribute with default types?
