This article provides some code samples in Rust.

Command line interface

Command arguments

cargo run foo bar baz "This string is a sentence"

1
use std::env;
2

3
// cargo run hello world
4

5
fn main() {
6
    let args: Vec<String> = env::args().collect();
7

8
    // Retrieve first argument
9
    let input = args[1].clone();
10

11
    // Print all arguments
12
    println!("{:?}", args); // ["target/debug/executable", "foo", "bar", "baz", "This string is a sentence"]
13
}

Standard input

1
use std::io;
2

3
fn main() {
4
    // empty string
5
    let mut input = String::new();
6

7
    // Collecting user input
8
    println!("Enter your name: ");
9
    io::stdin()
10
        .read_line(&mut input)
11
        .expect("Failed to read line");
12

13
    println!("Received name: {}", input);
14
}

During the last months, I worked on uvt-rs, my first project in Rust 🦀!

uvt-rs is a collection of Rust crates for processing and interacting with Uncrewed Vehicle Trajectory (UVT) files. The UVT file format provides a lightweight way to describe trajectories of uncrewed vehicles, such as UAV, UGV, etc. It was designed as an extension of the LTR format introduced in Kilometer-Scale Autonomous Navigation in Subarctic Forests: Challenges and Lessons Learned.

The repository includes three crates:

• uvt, to read, write, and generate UVT files from ROS bags (.bag) and MCAP files
• uvt-plot, to plot a bird's-eye view of recorded trajectories
• uvt-viz3d, to visualize UVT files in 3D with rerun

Through this project, I learned a lot about coding and packaging Rust crates, and I gained experience with deserializing messages from both ROS bag and MCAP formats. I'm now looking forward to more opportunities to use Rust for robotics projects!
