nom_stl is a binary and ASCII STL parser, written in pure Rust, with only one runtime dependency: the nom parser combinator library. nom_stl automatically differentiates between ASCII and binary STLs. It parses a 30M binary STL in <20ms.

let file = std::fs::File::open("./fixtures/Root_Vase.stl").unwrap();
let mut root_vase = BufReader::new(&file);
let mesh: Mesh = parse_stl(&mut root_vase)?;
assert_eq!(mesh.triangles.len(), 596_736);

nom_stl accepts STL bytes in a wide variety of argument formats: it will try to parse any collection of bytes that implements Read and Seek.

$ cargo test

To make the tests run faster (but increase build time), you can run the tests in release mode. To do this, run the following:

$ cargo test --release

$ cargo bench
