Struct Callsign 

pub struct Callsign { /* private fields */ }

An APRS callsign with an optional SSID.

The SSID is usually a numeric 0–15 (as in AX.25) but APRS-IS and D-STAR gateways also use short alphanumeric SSIDs such as -S or -B. Both the base call and SSID are stored as uppercase ASCII in fixed-size inline buffers — no heap allocation.

Implementations

impl Callsign

pub fn decode_textual(input: &[u8]) -> Result<Self, AprsError>

Parse a textual callsign (e.g. W1AW-9, or a D-STAR K0HRV-S).

pub fn decode_ax25(bytes: &[u8]) -> Result<(Self, bool), AprsError>

Decode a 7-byte AX.25 address field.

AX.25 stores each character left-shifted by one bit. The SSID byte encodes the SSID in bits 1–4 and the end-of-address (EOA) flag in bit 0. Returns (callsign, eoa).

pub fn as_str(&self) -> &str

pub fn ssid(&self) -> Option<&str>

The SSID in textual form (e.g. "9", "S"), or None for no SSID.

pub fn ssid_numeric(&self) -> Option<u8>

The SSID as a number, if it is numeric (0–15). Returns None for no SSID or for an alphanumeric (e.g. D-STAR) SSID.

pub fn encode_textual(&self, out: &mut Vec<u8>)

Write this callsign in textual APRS format.

pub fn encode_ax25(&self, out: &mut Vec<u8>, eoa: bool)

Write this callsign as a 7-byte AX.25 address field.

AX.25 can only represent numeric SSIDs 0–15; an alphanumeric SSID (only valid in textual/APRS-IS form) is encoded as SSID 0.

Trait Implementations

impl Clone for Callsign

fn clone(&self) -> Callsign

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Callsign

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

Formats the value using the given formatter.

impl Display for Callsign

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

Formats the value using the given formatter.

impl Hash for Callsign

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Callsign

fn eq(&self, other: &Callsign) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
