Bindings to the Swift GPS library (gps/).
This crate exposes the bindings module to access the C functions and statics directly.
However, intended usage is through the Gps struct, which provides a safe wrapper for the unsafe C items.
This type exposes safe bindings with respect to the (kinda undocumented) safety constraints of the C code. Previous testing shows that violating these unspoken invariants can result in all kinds of weird behavior!
In short, you can use the various methods on Gps to interact with the Rover's GPS system.
use gps_rs::Gps;
// we can make a GPS from a given IP address and port.
//
// on the Rover, this is from the router (hopefully a static IP) and a port
let swift_ip: IpAddr = "192.168.1.222".parse().unwrap();
let swift_port: u16 = 55556;
// here, we make the GPS! this will automatically initialize it.
let gps: Gps = Gps::new(swift_ip, swift_port).unwrap();
// now, you can use its methods:
println!("coord: {:?}", gps.coord());
println!("height: {:?}", gps.height());
println!("error in mm: {:?}", gps.error());
// dropping it (when it falls from scope) automatically runs the required cleanup.Unimplemented. This should use the pyo3 feature to build, and I'll plan to upload it to PyPi soon.
