import gltf in rust

To import glTF (GL Transmission Format) files in Rust, you can use the gltf crate which provides a safe, convenient, and efficient API for reading and writing glTF 2.0 files.

Here's an example code snippet that demonstrates the basic usage of the gltf crate for importing a glTF file:

main.rs
extern crate gltf;

use std::fs::File;
use std::io::BufReader;

fn main() {
    let file = File::open("path/to/my_model.gltf").unwrap();
    let reader = BufReader::new(file);
    let gltf = gltf::Gltf::from_reader(reader).unwrap();

    // Access glTF model data (e.g. meshes, materials, nodes, etc.)
    for scene in gltf.scenes() {
        for node in scene.nodes() {
            // Process node data (e.g. transform, meshes, etc.)
            // ...
        }
    }
}

In this example, we first open the glTF file using File::open and read its contents with BufReader. Then, we use gltf::Gltf::from_reader to parse the glTF data into a Gltf struct. Finally, we can access the glTF model data (e.g. meshes, materials, nodes, etc.) by iterating over scenes and nodes, as shown in the example.

Note that the gltf crate also supports loading glTF binary (.glb) files and provides many other features for advanced use cases. See the crate's documentation for more information.
