Struct PacketBytesMessage 

pub struct PacketBytesMessage;

Variable-length byte-payload codec. See module docs for the bit layout.

Trait Implementations

impl Clone for PacketBytesMessage

fn clone(&self) -> PacketBytesMessage

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PacketBytesMessage

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PacketBytesMessage

fn default() -> PacketBytesMessage

Returns the “default value” for a type.

impl MessageCodec for PacketBytesMessage

const PAYLOAD_BITS: u32 = 91

91 information bits matching Ldpc174_91’s K. Of those, 4 bits are length, 80 bits are up to 10 bytes of payload, and the final 7 bits are a CRC-7 over the head 84 bits.

const CRC_BITS: u32 = 7

CRC-7 trailing the payload — x^7 + x^3 + 1 over bits 0..84. The 7-bit CRC sits at info bits 84..91. See the private crc7 helper in this module / Self::verify_info.

fn verify_info(info: &[u8]) -> bool

Verify the CRC-7 trailer. Called by the FEC layer (BP / OSD) to reject parity-converged candidates whose CRC doesn’t match — substantially reduces the false-decode rate over the naive “always accept” verifier.

type Unpacked = Vec<u8>

Decoded high-level representation returned by unpack.

fn pack(&self, fields: &MessageFields) -> Option<Vec<u8>>

Encode high-level fields to a bit vector of length PAYLOAD_BITS. Returns None on encoding failure (invalid callsign format, overflow…).

fn unpack(&self, payload: &[u8], _ctx: &DecodeContext) -> Option<Self::Unpacked>

Decode a PAYLOAD_BITS-long bit vector to the protocol-specific unpacked representation. ctx carries side information such as the callsign-hash table.
