Zerocopy will be easy to implement now that I’ve found out how it is done by experimenting with basic types.

Memory requirements are relaxed as in:

  1. Before (0.10.x): stack is required for the artifact
  2. After (0.11.x): a CPU with registers will do for the memory, and read-only address for the input data.

70-80% of code base will be re-usable and remaining 20% is rewriting macros, tweaking a few call sites and creating a few new traits for macro consumption.

Despite 0.10.x having clone semantics, it is the correct traversal that is the hard problem here and it needs to be solved only once that data can be used to inject slice markers to exactly correct locations. This is why also parsing or building process nees no extra memory other than CPU cores registers.

The number lines in implementation will with higher odds go down rather than up. Looking pretty good…
