NMEA Parser for Rust

This Rust crate aims to cover all AIS sentences and the most important GNSS sentences used with NMEA 0183 standard. It supports both AIS class A and class B.

Usage

Include the following fragment in your Cargo.toml file:

[dependencies]
nmea-parser = "0.10.0"

The following example code fragment uses the crate to parse the given NMEA sentences and to print some parsed fields. It relies on unwrap() function to simplify the example. In real-life applications proper handling of None cases is needed.

use nmea_parser::*;

// Create parser and define sample sentences
let mut parser = NmeaParser::new();
let sentences = vec![
  "!AIVDM,1,1,,A,H42O55i18tMET00000000000000,2*6D",
  "!AIVDM,1,1,,A,H42O55lti4hhhilD3nink000?050,0*40",
  "$GAGGA,123519,4807.038,N,01131.000,E,1,08,0.9,545.4,M,46.9,M,,*56",
];

// Parse the sentences and print some fields of the messages
for sentence in sentences {    
    match parser.parse_sentence(sentence)? {
        ParsedMessage::VesselDynamicData(vdd) => {
            println!("MMSI:    {}",        vdd.mmsi);
            println!("Speed:   {:.1} kts", vdd.sog_knots.unwrap());
            println!("Heading: {}°",       vdd.heading_true.unwrap());
            println!("");
        },
        ParsedMessage::VesselStaticData(vsd) => {
            println!("MMSI:  {}", vsd.mmsi);
            println!("Flag:  {}", vsd.country().unwrap());
            println!("Name:  {}", vsd.name.unwrap());
            println!("Type:  {}", vsd.ship_type);
            println!("");
        },
        ParsedMessage::Gga(gga) => {
            println!("Source:    {}",     gga.source);
            println!("Latitude:  {:.3}°", gga.latitude.unwrap());
            println!("Longitude: {:.3}°", gga.longitude.unwrap());
            println!("");
        },
        ParsedMessage::Rmc(rmc) => {
            println!("Source:  {}",        rmc.source);
            println!("Speed:   {:.1} kts", rmc.sog_knots.unwrap());
            println!("Bearing: {}°",       rmc.bearing.unwrap());
            println!("Time:    {}",        rmc.timestamp.unwrap());
            println!("");
        },
        _ => {
        }
    }
}

The example outputs the following lines:

MMSI:  271041815
Flag:  TR
Name:  PROGUY
Type:  passenger

Source:    Galileo
Latitude:  48.117°
Longitude: 11.517°
