Hi! I'm sorry, but I think that bit7z, as it is currently implemented, is not a suitable or ideal solution for your use case. The main problems are:

• bit7z is a static library; maybe, there will also be a header-only version of it in the future, but not soon.
• The current version supports only Windows, so it would probably not run on an edge device.
• The next major version (i.e., v4.0) will also support Unix operating systems (e.g., Linux and macOS), but it will always be a simple interface to the 7-zip (or p7zip) shared libraries:
  • bit7z doesn't contain the source code for parsing archives: instead, it uses the interfaces provided by 7-zip for performing the requested operations; the actual code for reading archives is inside the shared library you use along with bit7z (e.g., 7z.dll or 7z.so).
  • Maybe it is possible to compile a customized shared library of 7-zip that supports only the tar format (I don't know if it is possible, tbh). However, its resource usage might not be suitable for an edge device (as far as I know, 7-zip is mainly designed to run on desktop environments).
