Python embed Examples

Example #1

File: test_hex.py Project: psobot/packing-tape

class MyStruct(Struct):
    int_a = integer(signed=False, endianness=Big)

    empty_space = empty(size=3)

    bits = bitfield(
        empty(),
        bit(),
        empty(size=5),
        bit(),
    )

    bit_a, bit_b = bits.expand()

    embedded = embed(EmbeddedStruct, default=EmbeddedStruct(2, 3, 4, 5))

Example #2

class ComplexSwitchStruct(Struct):
    value = one_of(embed(EmbeddedSwitchStruct1), embed(EmbeddedSwitchStruct2))

Example #3

File: test_embed.py Project: psobot/packing-tape

class EmbedStruct(Struct):
    struct_a = embed(IntStruct)
    int_b = integer(signed=False, endianness=Big)

Example #4

File: test_valid.py Project: psobot/packing-tape

class ValidStruct(Struct):
    int_a = integer(signed=False, endianness=Big, validate=lambda x: x < 50)
    int_b = integer(signed=False, endianness=Big, validate=lambda x: x > 50)
    embedded = embed(IntStruct, default=IntStruct(signature=1234))

Example #5

File: test_exs24.py Project: psobot/packing-tape

class EXSParam(Struct):
    object_header = embed(
        EXSObjectHeader,
        validate=lambda header: header.type_signature in (0x04000101,))
    unknown = empty(472 - EXSObjectHeader.min_size())

Example #6

File: test_exs24.py Project: psobot/packing-tape

class EXSSample(Struct):
    object_header = embed(
        EXSObjectHeader,
        validate=lambda header: header.type_signature in (0x03000101,))
    unknown = empty(676 - EXSObjectHeader.min_size())

Example #7

File: test_exs24.py Project: psobot/packing-tape

class EXSGroup(Struct):
    object_header = embed(
        EXSObjectHeader,
        validate=lambda header: header.type_signature in (0x02000101,))
    unknown = empty(216 - EXSObjectHeader.min_size())
