Struct Q65Message 

pub struct Q65Message;

Q65 MessageCodec — wire-compatible with Wsjt77Message at the human-readable level (Q65 transmits standard FT-style callsign / grid / report messages and free text), but advertises the Q65-specific CRC-12 width as metadata.

The 77-bit ↔ 13-symbol conversion (which is the Q65-specific piece) lives as free functions in this module (pack77_to_symbols / unpack_symbols_to_bits77) and is invoked from the protocol’s tx / rx paths, not through this trait.

Trait Implementations

impl Clone for Q65Message

fn clone(&self) -> Q65Message

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Q65Message

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

Formats the value using the given formatter.

impl Default for Q65Message

fn default() -> Q65Message

Returns the “default value” for a type.

impl MessageCodec for Q65Message

const PAYLOAD_BITS: u32 = 77

Q65 carries the same 77-bit WSJT payload as FT8 / FT4 / FST4.

const CRC_BITS: u32 = 12

Q65 protects the payload with a CRC-12 (vs the 14-bit CRC FT8/FT4 use). The CRC sits inside the QRA codec — see crate::fec::qra::Q65Codec.

type Unpacked = String

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.

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

Verify the integrity of post-FEC info bits. The FEC layer invokes this when a candidate codeword satisfies parity: returning true accepts the codeword; returning false causes the FEC to keep iterating.
