Hi
We used Cap'n Proto to serialize data in a shared memory environment and
defined some message types as structs containining List, i.e.
struct Message{
points @0 List(Vector3f)
};
Where Vector3f is another struct containing either 3 floats or a
List(Float32). However, extracting the Vecto
Hi Philipp,
This is a bit of an unusual case, where I imagine you are working with bulk
vector data forming a 3D mesh or some such, and in order to hand if off to
the graphics card, you really need a direct pointer to the underlying data
and you need it to be in a specific layout.
Using Data is t
Hi Kenton
Thanks a lot for this amazingly fast reply and the explanations.
We might try the direct pointer approach and it's very useful to know this
possibility but for now I think having the data in a Data member seems to
be working.
Cheers!

I want to ask a related question, and found out this thread.
>From what I understand in the discussion, if I have
struct Vector3d {
x @0 :Float64;
y @1 :Float64;
z @2 :Float64;
}
and then
struct Point3Array {
data @0 :List(Vector3d);
}
Will i get a perfectly packed array of Vector3d in memory
Another comment, I would also agree probably using raw data as the type is
more appropriate, with a metadata information to encode the endianess.
This would be similiar
