Crate python_packed_resources

Python Packed Resources

This crate defines and implements a data format for storing resources useful to the execution of a Python interpreter. We call this data format Python packed resources.

The idea is that a producer collects Python resources required by a Python interpreter - Python module source and bytecode, non-module resource files, extension modules, shared libraries, etc - attaches metadata to those resources (e.g. whether a Python module is also a package), and then serializes all of this out to a binary data structure.

Later, this data structure is parsed back into composite parts. e.g. to a mapping of Python module names and their respective data. This data structure is then consulted by a Python interpreter to e.g. power the module import mechanism.

This crate is developed primarily for PyOxidizer. But it can be used outside the PyOxidizer project.
