CModel

Model C structs with Pydantic

cmodel lets you describe C-compatible binary layouts with normal Pydantic models. You keep Pydantic's validation and nested models, and gain a simple way to pack and unpack structs from binary buffers.

Quick start

from io import BytesIO

from cmodel import CModel
from cmodel.types import Int


class Point(CModel):
	x: Int
	y: Int


buf = BytesIO()
Point(x=3, y=7).c_pack(buf)

buf.seek(0)
point = Point.c_unpack(buf)

assert point == Point(x=3, y=7)
assert buf.getvalue() == b"\x03\x00\x00\x00\x07\x00\x00\x00"
