Crate openusd 

Native Rust implementation of Universal Scene Description (USD).

Reads .usda (text), .usdc (binary), and .usdz (packaged) files without any C++ dependencies.

Modules

Module	Purpose
sdf	Core data model — Value, Path, Spec, AbstractData trait, and schema field keys.
usda	Text format reader. TextReader parses .usda files into AbstractData.
usdc	Binary format reader. CrateData parses .usdc files into AbstractData.
usdz	Archive format reader. Archive extracts layers from .usdz packages.
ar	Asset resolution. Resolver trait maps asset paths (@...@) to physical locations; DefaultResolver searches the filesystem.
layer	Layer collection. collect_layers recursively loads all layers from a root file.
pcp	Prim Cache Population — the composition engine. Implements LIVRPS strength ordering, per-prim index caching, and namespace mapping via MapFunction.
stage	Composed stage. Stage merges opinions across layers using LIVERPS strength ordering.
expr	Variable expression parser and evaluator for USD’s \…`` expression syntax.

Quick start

use openusd::Stage;

let stage = Stage::open("scene.usda").unwrap();

stage.traverse(|prim_path| {
    println!("{prim_path}");
}).unwrap();

Re-exports
