copper-value

copper-value provides a way to capture serialization value trees for later processing. Customizations are made to enable a more compact representation for the structured logging of copper.

Python Feature

With the python feature enabled, this crate also provides conversion helpers between cu29_value::Value and Python objects via PyO3.

That bridge is used in two places:

• cu-python-task, where Copper temporarily converts task inputs/state/outputs so a Python function can mutate them
• cu29-export, where Copper data is exposed to Python for offline analysis

Conversion behavior is intentionally simple:

• None maps to Value::Unit
• Python lists and tuples map to Value::Seq
• Python dicts map to Value::Map
• Python integers are accepted up to 128-bit signed/unsigned range
• Python bytes maps to Value::Bytes
