Module codec 

Wire-format codec for LoRaWAN packets.

Two halves to the API:

• Parsing: LoraPacket::from_wire takes raw bytes and returns a typed LoraPacket. Match on LoraPacket::payload (a Payload enum) to dispatch on the message variant.
• Building: LoraPacket::builder returns a LoraPacketBuilder that finalises with LoraPacketBuilder::sign_and_encrypt (Data), LoraPacketBuilder::sign_join_request (Join Request 1.0), LoraPacketBuilder::sign_join_request_v1_1 (Join Request 1.1), or LoraPacketBuilder::sign_join_accept (Join Accept).

All wire bytes are little-endian; struct fields display in big-endian order. The codec reverses bytes for you on both parse and serialise.

Structs

Data

Fields of a Data message (confirmed or unconfirmed, uplink or downlink).

JoinAccept

Fields of a Join Accept (plaintext, after decrypt).

JoinRequest

Fields of an OTAA Join Request.

LoraPacket

A LoRaWAN PHYPayload, parsed into structured fields.

LoraPacketBuilder

Fluent builder for assembling a LoraPacket field by field.

Enums

Payload

Discriminated union over the five LoRaWAN message variants.

RejoinRequest

Rejoin Request body (LoRaWAN 1.1).
