Struct ApHint 

pub struct ApHint {
    pub call1: Option<String>,
    pub call2: Option<String>,
    pub grid: Option<String>,
    pub report: Option<String>,
}

A Priori information to bias decoding.

Fields

call1: Option<String>

Known first callsign (e.g. “CQ”, “JA1ABC”). Locks message bits 0–28.

call2: Option<String>

Known second callsign (e.g. “3Y0Z”). Locks message bits 29–57.

grid: Option<String>

Known grid locator (e.g. “PM95”). Locks bits 58–73.

report: Option<String>

Known response token: “RRR”, “RR73”, or “73”. Locks bits 58–73.

Implementations

impl ApHint

pub fn new() -> Self

pub fn with_call1(self, call: &str) -> Self

pub fn with_call2(self, call: &str) -> Self

pub fn with_grid(self, grid: &str) -> Self

pub fn with_report(self, rpt: &str) -> Self

pub fn has_info(&self) -> bool

True if any AP field is populated.

pub fn build_bits(&self, n_codeword: usize) -> (Vec<u8>, Vec<u8>)

Build the (mask, bit_values) bit vectors of length n_codeword for a downstream FEC codec. Bits 0–76 (the message payload) are populated from the hint fields; bits 77..N are left unmasked.

mask[i] == 1 means bit i is AP-locked; values[i] is the target bit value (0 or 1). The FEC codec clamps its LLR at these positions to ±apmag accordingly.

pub fn locked_bits(&self, n_codeword: usize) -> usize

Number of AP-locked message bits (informational; callers use it to scale per-pass confidence thresholds).

Trait Implementations

impl Clone for ApHint

fn clone(&self) -> ApHint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ApHint

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

Formats the value using the given formatter.

impl Default for ApHint

fn default() -> ApHint

Returns the “default value” for a type.
