From c3a18d74ebebe1c68955c3dce3c782af949aa4c7 Mon Sep 17 00:00:00 2001 From: Damien George Date: Mon, 20 Jan 2025 22:24:10 +1100 Subject: extmod/modmarshal: Add new marshal module. This commit implements a small subset of the CPython `marshal` module. It implements `marshal.dumps()` and `marshal.loads()`, but only supports (un)marshalling code objects at this stage. The semantics match CPython, except that the actual marshalled bytes is not compatible with CPython's marshalled bytes. The module is enabled at the everything level (only on the unix coverage build at this stage).
