Does anybody know about an automatic SOA-builder library in Nim? Ideally I would like something like this:
type
Thing[T] = object
position: Vec3d[T]
orientation: Quaternion[T]
ThingArrAos[N: static[int], T] = array[N, Thing[T]]
ThingArrSoa[N: static[int], T] = arraySoa[N, Thing[T]]
...
let a = newGridArrAos(Thing(...), 4)
# in memory: Vec3d[T], Quaternion[T], Vec3d[T], Quaternion[T], Vec3d[T], Quaternion[T], Vec3d[T], Quaternion[T]
let s = newGridArrSoa(Thing(...), 4)
# in memory: Vec3d[T], Vec3d[T], Vec3d[T], Vec3d[T], Quaternion[T], Quaternion[T], Quaternion[T], Quaternion[T]
Of course things like:
# generates ThingArrSoa type
defSoa type ThingArrSoa[N: static[int], T] = arraySoa[N, Thing[T]]
# generates array, dynamic array (casual seq is a little pointless) and similar types (handy!)
defSoa Thing[T]
