Crate openusd_schemas 

Typed views for USD’s standard schemas, over a composed Stage.

Ask a Mesh for its points, a Camera for its focal length, a Material for the shader on its surface output, a Skeleton for its joints and skinning weights — as Rust types, rather than by attribute name and hand decoding. Every view authors as well as reads.

Each sub-module is feature-gated so callers only compile what they need:

Feature	Module	Status
geom	geom	UsdGeom reader (cross-cutting Imageable / Boundable today; full surface incoming).
physics	physics	UsdPhysics reader (8 prim types, 7 single-apply APIs, multi-apply LimitAPI / DriveAPI).
skel	skel	UsdSkel trait-views (SkelRoot / Skeleton as geom Boundable, SkelAnimation / BlendShape typed, SkelBindingAPI single-apply) + skinning toolkit (Topology, AnimMapper, SkeletonResolver, SkinningResolver, pure-math LBS); builds on the geom trait chain.
lux	lux	UsdLux trait-views (8 concrete light prims + LightFilter + LightAPI / ShapingAPI / ShadowAPI / LightListAPI); builds on the geom trait chain.
shade	shade	UsdShade trait-views (Shader / NodeGraph / Material via the Connectable interface, MaterialBindingAPI, UsdPreviewSurface reader).
render	render	UsdRender trait-views (RenderSettings / Product via the RenderSettingsBase interface, Var / Pass / DenoisePass) + the computed render spec.
ui	ui	UsdUI trait-views (typed Backdrop + single-apply SceneGraphPrimAPI / NodeGraphNodeAPI).
vol	vol	UsdVol trait-views (Volume + OpenVDBAsset / Field3DAsset); builds on the geom trait chain.
media	media	UsdMedia trait-views (SpatialAudio + AssetPreviewsAPI); builds on the geom trait chain.
proc	proc	UsdProc trait-view (GenerativeProcedural, a geom::Boundable); builds on the geom trait chain.

These views read and author opinions; the property fallbacks a schema declares come from openusd::usd::SchemaRegistry.

SchemaError

Any failure a schema view can report: a schema-domain failure of its own, or a core failure (Core) from the composed queries and authoring calls the view is built on.
