Rust API¶

The cosmol_viewer crate is the public Rust facade. It re-exports the shared scene, animation, renderer, shape, and COSMolKit APIs used by the Python and WebAssembly packages.

use cosmol_viewer::{ImageRenderer, Scene, shapes::Molecule};

fn main() -> Result<(), Box<dyn std::error::Error>> {
    let molecule = Molecule::from_sdf(include_str!("molecule.sdf"))?
        .centered()
        .enable_outline(0.04);

    let mut scene = Scene::new();
    scene.add_shape_with_id("molecule", molecule);
    ImageRenderer::save_png(&scene, "molecule.png", 1200, 900)?;
    Ok(())
}

The complete generated Rust reference is published on docs.rs. Rust examples are maintained in the repository’s cosmol_viewer/examples directory.
