Rerun

Rust

Setup setup

The Rerun SDK for Rust requires a working installation of Rust 1.79+.

After you have installed the viewer you can simply add the Rerun crate to your project with cargo add rerun.

Let's try it out in a brand new Rust project:

$ cargo init cube && cd cube && cargo add rerun

Logging some data logging-some-data

Add the following code to your main.rs (This example also lives in the rerun source tree example)

use rerun::{demo_util::grid, external::glam};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let rec = rerun::RecordingStreamBuilder::new("rerun_example_minimal").spawn()?;

    let points = grid(glam::Vec3::splat(-10.0), glam::Vec3::splat(10.0), 10);
    let colors = grid(glam::Vec3::ZERO, glam::Vec3::splat(255.0), 10)
        .map(|v| rerun::Color::from_rgb(v.x as u8, v.y as u8, v.z as u8));

    rec.log(
        "my_points",
        &rerun::Points3D::new(points)
            .with_colors(colors)
            .with_radii([0.5]),
    )?;

    Ok(())
}

Now run your application:

cargo run

Once everything finishes compiling, you will see the points in the Rerun Viewer:

Using the Viewer using-the-viewer

Try out the following to interact with the viewer:

  • Click and drag in the main view to rotate the cube.
  • Zoom in and out with the scroll wheel.
  • Mouse over the "?" icons to find out about more controls.
  • Click on the cube to select all of the points.
  • Hover and select individual points to see more information.

If you're facing any difficulties, don't hesitate to open an issue or join the Discord server.
