Python struct staticfield数据类型的新构造2.9语法

我使用构造2.5.2实现了这一点：

something=Struct("somename",
Bytes("version",4),
StaticField("somefieldname",32)
)

myVar=something.parse('John')
myVar.version=struct.pack('<I',1)
myVar.somefieldname=struct.pack('<qqqq',0,0,0,0)

---

我用来存储新构造版本中调用的struct.pack结果的旧“StaticField”是什么？

StaticField

类在v中不再可用。2.9. 下面是使用

construct 2.9

语法的示例：

from construct import Int, Struct, GreedyString

# create struct
my_struct = Struct(
    "version" / Int,
    "somefieldname"/ GreedyString(encoding='utf-8')
)

# build an object in memory (a bytes object).
build = my_struct.build(dict(version=1, somefieldname="John"))

assert build == b'\x00\x00\x00\x01John'

# parse an in-memory buffer
parsed_data = my_struct.parse(build)

assert parsed_data.version == 1
assert parsed_data.somefieldname == "John"

---

有大量的示例介绍如何使用不同的数据类型。

感谢您的编辑，我现在为将来使用的样式：-）

from construct import Int, Struct, GreedyString

# create struct
my_struct = Struct(
    "version" / Int,
    "somefieldname"/ GreedyString(encoding='utf-8')
)

# build an object in memory (a bytes object).
build = my_struct.build(dict(version=1, somefieldname="John"))

assert build == b'\x00\x00\x00\x01John'

# parse an in-memory buffer
parsed_data = my_struct.parse(build)

assert parsed_data.version == 1
assert parsed_data.somefieldname == "John"
