Rough ideas.

• Treat _pad as padding members and automatically initiallize it in init struct. This requires moving the pad field as a member in struct member entry info to a member entry variant type?

• Allow injecting dynamic shader defines at build-time (we already have a runtime mechanism from generation)

• Allow generation directly from shader strings.

• proc_macro as an option alongside of build.rs. We need proc_macro::tracked* feature?

• Use something like derivative and use MaybeUninit for padded fields

• Use rustfmt instead of prettyparse

• Use struct like this instead directly using the array.

  • #[repr(C)]
    struct PaddedField<const N: usize, T> {
        field: T,
        padding: [u8; N],
    }
    
    impl<const N: usize, T> PaddedField<N, T> {
      pub fn new(value: T) -> Self {
        Self {
          field: value,
          padding: [0; N],
        }
      }
    }

• Add a way to encode variant types in wgsl?.

  • Maybe a seperate binary that accepts rust source.
  • Generates accessors, setters in wgsl
  • Struct fields are efficiently utilised.
