Now it is just POC to have thin C layer only for agama purpose on top of libzypp.

Repo Organization

Repository contains three directories:

• c-layer that contain sources to build static library and in include directory C ready headers. The internal directory contains C++ headers that is used only for inter-communication and is private.
• c-example is example pure C binary that is using static library and produce some output
• rust is target rust code that should be used from Agama, but it is not ready yet.

Libzypp Notes

• libzypp is not thread safe
• for seeing how it works see yast2-pkg-bindings and zypper as some parameters in calls are ignored
• goal is to have thin layer close to libzypp and build logic on top of it in more advanced language
