destruct

Destruct is a tiny library to declaratively define data structures and parse them to Python objects.

The library is not mature by any means. Things may break, and API may significantly change in future.

Example

Data structures are declared in a manner somehow similar to Django models:

from destruct import StructBase
import destruct.fields as f

class MyStruct(StructBase):
    timestamp = f.TimestampField()
    value = f.U32Field()

Then, parsing is just creating object:

data = MyStruct(b"\0\0\0\0\0\0\0\xFF")
assert data.timestamp == datetime.datetime.utcfromtimestamp(0)
assert data.value == 255
