Rust bindings for RTIMULib2

Rust bindings for RTIMULib2 generated with https://rust-lang.github.io/rust-bindgen/

Steps to generate bindings:

• On Debian

sudo apt install llvm-dev libclang-dev clang

• clone and build RTIMULib2

cd ~
git clone https://github.com/seandepagnier/RTIMULib2
cd RTIMULib2/RTIMULib
mkdir build && cd build 
cmake ..
make

• put content of this directory under RTIMULib2/Linux/rust/

cd ~
git clone https://github.com/bareboat-necessities/rust-modules
cp -r rust-modules/RTIMULib2/Linux/rust ~/RTIMULib2/Linux/

• cargo build

cd ~/RTIMULib2/Linux/rust
cargo build
find . -name bindings.rs

• cargo test

cd ~/RTIMULib2/Linux/rust

The Rust code example:

use std::mem::MaybeUninit;
use std::os::raw::{c_void};
use std::{ptr, thread, time};
use rtimulib_rust::{RTIMUSettings, RTIMU, RTIMUSettings_RTIMUSettings, RTIMUMPU925x_IMUInit, RTIMUMPU925x_IMUGetPollInterval, RTMath_displayDegrees, RTVector3, RTIMUMPU925x_IMURead, RTIMUMPU925x_RTIMUMPU925x_destructor, RTIMUMPU925x, RTFusionKalman4_RTFusionKalman4_destructor, RTFusionKalman4};

fn main() {
    println!("Hello RTIMULib!");

    let mut instance = MaybeUninit::<RTIMUSettings>::uninit();
    let settings = instance.as_mut_ptr();

        (*settings).m_fusionType = 1;
        let imu = RTIMU::createIMU(settings);

        (*fusion).m_enableGyro = true;
        (*fusion).m_enableAccel = true;
        (*fusion).m_enableCompass = true;

        let poll = RTIMUMPU925x_IMUGetPollInterval(imu as *mut c_void);
        println!("Poll: {}", poll);

        let deg = RTMath_displayDegrees("".as_ptr(), p_pose);
        println!("{}", CStr::from_ptr(deg).to_str().unwrap().to_owned());

        RTFusionKalman4_RTFusionKalman4_destructor(fusion as *mut RTFusionKalman4);
