Make Packet pull its weight: type indexing, hashing, delete .payload - #130
Merged
Conversation
Packet[TCP] returns the first matching layer in wire order (KeyError on no match); Packet.get(TCP) returns None instead. packet[0] keeps indexing positionally — __getitem__ branches on int vs type. Packet.__hash__ mirrors exactly what __eq__ already compares (layers, and stopped_by's type + str(), not identity, since ProtocolError has no custom __eq__), so Packet is now usable as a dict key or set member. BREAKING: Packet.payload is deleted outright. It was always exactly bytes(self), a redundant duplicate of __bytes__/bytes(packet), which is the unambiguous spelling. This is the breaking change behind the 2.0.0 major bump. Closes#90. Co-Authored-By: Claude <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SVCFe7B1U5VeJRoUbx24vb
Adds the packet[TCP] / packet.get(TCP) example alongside the existing packet[1] positional one in the decode_frame() walkthrough (#90). Co-Authored-By: Claude <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01SVCFe7B1U5VeJRoUbx24vb

Summary
Closes#90.
Packetgains type-keyed access and becomes hashable; the redundant.payloadproperty is deleted, which is the breaking change behind the 2.0.0 major bump (Tier 2, #104).What's included
Packet.__getitem__branches onint(unchanged positional indexing) vs. a protocol type (packet[TCP]returns the first matching layer in wire order,KeyErroron no match).Packet.get(TCP)— same lookup, returnsNoneon no match instead of raising (dict-like.get()convention).Packet.__hash__, mirroring exactly what the existing__eq__compares (layers, andstopped_by's type andstr(), not identity —ProtocolErrorhas no custom__eq__).Packetis now usable as a dict key or set member.Packet.payloadis deleted outright (not deprecated). It was always exactlybytes(self), a redundant duplicate of__bytes__/bytes(packet), which is the unambiguous spelling and already existed.tests/test_packet.py: type-key hit/miss, int-key hit/miss (unchanged),.get()hit/miss, hash consistency with==(equal packets hash equal,stopped_bychanges the hash),Packetas a dict key / set member,.payloadraisesAttributeError.CHANGELOG.mdentry under## [Unreleased](### Removedfor the breaking change,### Addedfor the new capabilities).Verification

Notes
Per the roadmap's working agreement (#107), this is the first of three remaining Tier 2 issues (#90 → #89 → #92) — merged one at a time, not auto-merged.
