How to contribute

We have an ongoing effort to support as many sentences from NMEA 0183 as possible, starting with the most well-known. If you'd like to contribute by writing a parser for a given message, check out the Supporting additional sentences (AeroRust/nmea#54) issue and contribute in 3 easy steps:

1. Write a comment - Please write a comment in the issue for the sentence(s) you'd like to implement, you will be mentioned on the task to avoid duplicate implementations.
2. Implement each sentence alongside at least 1 test in its own module under the ./src/sentences directory using the nom crate.
3. Open a PR 🎉

What is NMEA 0183?

Usage

Add the nmea dependency in your Cargo.toml:

[dependencies]
nmea = "0.4"

For no_std

This crate support no_std without the use of an allocator ( alloc ), just add the nmea crate without the default features:

[dependencies]
nmea = {version = "0.4", default-features = false}

For Rust edition 2015

For Rust 2015 edition you should put this in your crate's lib.rs or main.rs:

extern crate nmea;

To use the NMEA parser create a Nmea struct and feed it with NMEA sentences (only supports GNSS messages, otherwise use the parse_str() and parse_bytes()):

use nmea::Nmea;

fn main() {
    let mut nmea = Nmea::default();
    let gga = "$GPGGA,092750.000,5321.6802,N,00630.3372,W,1,8,1.03,61.7,M,55.2,M,,*76";

    nmea.parse(gga).unwrap();
    println!("{}", nmea);
}
