xdrlib Module¶
⚠️ REMOVED IN PYTHON 3.13: The xdrlib module was deprecated in Python 3.11 and removed in Python 3.13.
The xdrlib module provides tools for XDR (External Data Representation) serialization, used for network communication.
Complexity Reference¶
| Operation | Time | Space | Notes |
|---|---|---|---|
Packer() |
O(1) | O(1) | Create packer (legacy) |
| Pack data | O(n) | O(n) | n = data size |
| Unpack data | O(n) | O(n) | n = buffer size |
XDR Serialization¶
Packing and Unpacking Data¶
import xdrlib
# Create packer - O(1)
p = xdrlib.Packer()
# Pack data - O(n)
p.pack_int(42)
p.pack_string('hello')
p.pack_list([1, 2, 3], p.pack_int)
# Get packed data - O(1)
data = p.get_buffer()
# Unpacking - O(n)
u = xdrlib.Unpacker(data)
num = u.unpack_int()
text = u.unpack_string()
nums = u.unpack_list(u.unpack_int)
