That is pretty amazing! I wonder how would it look like if it was written in C. Anyone has some links to "Blobs" implementations in C?

If you allow codegen in advance it looks pretty similar eg https://capnproto.org/cxx.html

I've used a protobuf library for Arduino that was zero copy... A lot of callbacks to do something with each new thing that's read.
