MT Serial Out Packet Format.

Fields

header: String

Header, should be MT1.

id: String

UUU - Three character MT-RX configurable ID – by default this is 001.

sequence_number: usize

NNN - Three decimal digit cycling packet sequence number from 000 to 511. This sequence number

message_type: char

T - Single character message type ‘T’ or ‘A’ (test or distress alert)

format_flag: char

F - Single character format flag S or L (short or long) – this relates to the 406 beacon transmission specification.

beacon: [u8; 15]

15 character hex code used to define beacon owner and beacon capabilities as per the 406 beacon specification.

signal_strength: [char; 2]

SS - Two character signal strength indication – 00 if not used.

lat_degrees: u8

11 - Two decimal character latitude degrees.

lat_minutes: u8

22 - Two decimal character latitude minutes.

lat_seconds: u8

33 - Two decimal character latitude seconds.

n: char

N - is N or S.

long_degrees: u16

444 - Three decimal character longitude degrees.

long_minutes: u8

22 - Two decimal character longitude minutes.

long_seconds: u8

55 - Two decimal character longitude seconds.

w: char

W - is W or E.

checksum: u16

YYYY - Four character checksum (calculated from M – the first character). If all location characters are ‘-’ then there is no location information available.

Implementations

impl MtStructured

pub fn is_mt(message: &str) -> bool

Returns whether message is a valid MT(1) message.

Examples

use wte_mt_rx_parser::mt_structured::MtStructured;
println!("is it MT1? {}", MtStructured::is_mt("MT1001000AL400C592753572B323433212S1723756E4706"));

pub fn parse(message: &str) -> Result<MtStructured, ParseError>

Tries to parse a “MT Serial Out Packet Format” message.

Notes

• Checksum is not calculated here.

Examples

use wte_mt_rx_parser::mt_structured::MtStructured;
let parsed = MtStructured::parse("MT1001000AL400C592753572B323433212S1723756E4706").unwrap();
// ...

Message format

Data provided should be in the following format:

• MT1UUUNNNTFHHHHHHHHHHHHHHHSS112233N4445566WYYYY

Trait Implementations

impl Clone for MtStructured

fn clone(&self) -> MtStructured

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MtStructured

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

Formats the value using the given formatter.

impl PartialEq for MtStructured

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

This method tests for self and other values to be equal, and is used by ==.

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

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