databind.binary 0.2.1

Bind object-oriented data models to binary data encoded with the struct module.

databind.binary

Databind is a library inspired by Jackson-databind to describe and bind data models for object-oriented programming. The databind.binary package implements conversion of data models between Python and binary format (using the struct module).

Todo

• Support (efficient) unpacking of nested structs

Quickstart

from databind.binary import to_bytes, calc_size, cstr, u32
from databind.core import datamodel, field

@datamodel
class RiffChunk:
  """ RIFF-WAVE chunk header. """
  chunk_id: cstr = field(default=b'RIFF', metadata={'size': 4})
  chunk_size: u32
  riff_type: cstr = field(default=b'WAVE', metadata={'size': 4})

assert calc_size(RiffChunk) == 12
assert to_bytes(RiffChunk(chunk_size=16442)) == b'RIFF:@\x00\x00WAVE'
