Crate gpsd_json 

gpsd-json

A Rust library for interfacing with GPSD (GPS Service Daemon) using its JSON protocol.

This library provides a pure Rust implementation for communicating with GPSD, parsing GPS data, and handling various data stream formats without requiring libgps.

Overview

GPSD is a service daemon that monitors one or more GPSes or AIS receivers attached to a host computer through serial or USB ports, making all data on the location/course/velocity of the sensors available to be queried on TCP port 2947 of the host computer.

This library implements the JSON-based protocol used by GPSD for client communication, supporting protocol version 3.x as defined in the GPSD project.

Example

use gpsd_json::client::{GpsdClient, StreamOptions};
use futures::StreamExt;

async fn example() -> Result<(), Box<dyn std::error::Error>> {
    // Connect to GPSD server
    let mut client = GpsdClient::connect("127.0.0.1:2947").await?;

    // Start streaming GPS data in JSON format
    let mut stream = client.stream(StreamOptions::json()).await?;

    // Process incoming GPS data
    while let Some(result) = stream.next().await {
        println!("Received: {:?}", result?);
    }
    Ok(())
}
