Command
Generate
tezzc pyext module.tn [out_dir] [--module name]The generator emits CPython wrapper C, an ABI header, setup metadata, ownership docs, and a deterministic wrapped/skipped manifest.
Python Bridge
Use Python for orchestration and TezzNative for native hot paths.
Milestone 6 adds a gated CPython extension scaffold generator for ABI-safe TezzNative functions.

Type Mapping
| TezzNative | Python Input | Python Return |
|---|---|---|
int / i64 | Python int | Python int |
u8 | Python int 0..255 | Python int |
float / f64 | Python float | Python float |
*char / *u8 parameter | Contiguous buffer object | Not returned |
void return | n/a | None |
Ownership
- Primitive values are copied between Python and TezzNative.
- Buffer parameters are borrowed with
PyObject_GetBufferonly for the call duration. - Borrowed buffers are released on success and error paths.
- Pointer returns, structs, and unsafe functions are skipped in the starter bridge.
