    InvalidOrTest(Vec<u8>),
}

A parsed APRS data frame, covering all major APRS data types.

Per APRS101.PDF, the data type is determined by the first byte of the AX.25 information field. This enum covers the types most relevant to the TH-D75’s APRS implementation.

Variants

Position(AprsPosition)

Position report (uncompressed, compressed, or Mic-E).

Message(AprsMessage)

APRS message addressed to a specific station.

Status(AprsStatus)

Status report (free-form text, optionally with Maidenhead grid).

Object(AprsObject)

Object report (named, with position and timestamp).

Item(AprsItem)

Item report (named, with position, no timestamp).

Weather(AprsWeather)

Weather report (temperature, wind, rain, pressure, humidity).

Telemetry(AprsTelemetry)

Telemetry report (analog values and digital status).

Query(AprsQuery)

Query (position, status, message, or direction finding).

ThirdParty

Third-party traffic — a packet originating elsewhere and forwarded by an intermediate station (APRS 1.0.1 §17). The header carries the original source>dest,path and the payload the original info field.

Fields

header: String

Raw source>dest,path header text from the third-party wrapper.

payload: Vec<u8>

Original APRS info field as bytes (no further parsing).

Grid(String)

Maidenhead grid locator (data type [). The string form is the 4-6 character grid square, e.g. "EM13qc" or "FM18lv".

RawGps(String)

Raw GPS sentence / Ultimeter 2000 data (data type $).

APRS 1.0.1 §5.2: anything starting with $GP, $GN, $GL, $GA (GPS/GNSS NMEA) or other $-prefixed instrument data. We store the full NMEA sentence minus the leading $.

StationCapabilities(Vec<(String, String)>)

Station capabilities report (data type <).

APRS 1.0.1 §15.2: comma-separated TOKEN=value tuples describing what the station supports (IGATE, MSG_CNT, LOC_CNT, etc.). We store them as a map.

AgreloDfJr(Vec<u8>)

Agrelo DFjr (direction-finding) data (data type %).

The library doesn’t interpret the binary format; we preserve the raw payload bytes for callers that do.

UserDefined

User-defined APRS data (data type {).

APRS 1.0.1 §18: format is {<experiment_id><type><data> where the experiment ID is one character. We split it out for convenience; callers that understand the experiment can parse the rest.

Fields

experiment: char

One-character experiment identifier (immediately follows {).

data: Vec<u8>

Everything after the experiment ID.

InvalidOrTest(Vec<u8>)

Invalid/test frame (data type ,).

Used for test beacons and frames that should be ignored by normal receivers. We preserve the payload for diagnostics.

Trait Implementations

impl Clone for AprsData

fn clone(&self) -> AprsData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AprsData

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

Formats the value using the given formatter.

impl PartialEq for AprsData

fn eq(&self, other: &AprsData) -> 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.

impl StructuralPartialEq for AprsData
