(TBD)
It’s convenient to be able to express structures as combinations of other structures as in Java/TypeScript.
wgsl-linker currently supports an extends syntax for struct inheritance (but extends is only lightly
used upstream).
Combining structures by simple composition is possible in standard WGSL. by referencing through a member field. But:
- Using fields of the referenced struct requires an additional field dereference "." in the syntax for each level of indirection.
- Some abstractions may be hard to express w/o inheritance (since we also don't have interfaces in WGSL).
Issues:
- TBD demonstrate an example or drop the feature.
- Also, would generics for structs be an alternate way to parameterize composition?
