Hello everyone! It took me about a month of vibe coding in my spare time to create the Draco library entirely in Rust. It wasn't easy and required a lot of patience, but I'm finally happy to share the code with everyone: https://github.com/Filyus/draco-rust

The current Rust crates live here:

I also wrote WASM modules and a sample web application for conversion: https://github.com/Filyus/draco-rust/tree/main/web

Current optimized WASM size comparison:

Module Raw gzip What is included
gltf_reader_bg.wasm 228.8 KiB 94.2 KiB Reads .gltf/.glb files, parses glTF JSON with serde_json, handles GLB containers, and decodes KHR_draco_mesh_compression payloads.
Google draco_decoder.wasm 1.5.7 279.2 KiB 86.5 KiB General Draco decoder for raw Draco buffers. No glTF JSON or GLB container handling.
Google draco_decoder_gltf.wasm 1.5.7 188.1 KiB 62.0 KiB Smaller Draco decoder subset for glTF KHR_draco_mesh_compression payloads. It decodes the extension's bufferView data but does not read .gltf/.glb files.

draco-core, draco-io, and draco-gltf are now published on crates.io, with CI, fuzzing, docs.rs builds, package verification, and GitHub release tags in place.
