Passing data without a copy between c++ and python

[lysander051]

Hi everyone,

I'm working on a project where I need to pass a kind of dict (which can be a custom data structure if required) with 2 int and a float to my C++ code.
The problem is that this structure will need to handle millions or more data. I'm looking for a way to pass this kind of data without a copy.

Is that even possible with Pybind and if yes do you have some documentation about it?

Thank you,
