Crate draco_gltf 

Full, lossless glTF 2.0 / pinned 2.1-draft model with Draco geometry.

Document is the public scene model, and all unknown JSON remains part of that model.

Modules

document

Lossless document model and typed views for glTF scenes. Lossless glTF document model and typed object views.

extensions

Extension contracts and resource storage used by document transforms. Extension contracts for the lossless document model.

Structs

AccessorData

Tightly packed accessor payload for geometry consumers.

CompressionOptions

Controls document-preserving Draco compression.

CompressionReport

Measured result of one Import::compress_primitive operation.

DocumentAccessorSource

Accessor source backed by a Document and its resolved resources.

FileResourceResolver

Filesystem resolver used by convenience file-loading APIs.

GeometryWriteOptions

Options controlling one geometry write operation.

GeometryWriteReport

Measured result of one atomic geometry write.

GlbRangeReader

Seekable, range-backed GLB source.

GltfOutput

A portable JSON glTF document and the companion resources it references.

GltfResource

One companion resource produced by Import::to_gltf_output.

Import

Lossless glTF document plus its resolved resources.

ImportOptions

Options controlling document loading, resource resolution and validation.

PackedAttribute

One materialized, tightly packed vertex attribute.

PackedGeometry

Materialized primitive geometry with contiguous attribute and index buffers.

PackedIndices

One materialized, tightly packed primitive index stream.

ResourceLimits

Optional resource quotas. None means unlimited.

Enums

CompressionMode

How the exported primitive exposes its Draco payload.

Error

Errors returned by glTF parsing and Draco operations.

ExternalFilePolicy

Policy used by FileResourceResolver.

GeometryEncoding

Storage selected for newly written primitive geometry.

GeometryError

Validation errors for materialized primitive geometry.

GltfContainerFormat

Container used by an input glTF document.

GltfError

Errors that can occur when reading, transforming, or decoding glTF data.

JsonValue

Lossless JSON value used by the document model. Dependency-free JSON value that preserves number lexemes and object order.

OutputFormat

Container representation selected when serializing an import.

PreserveReason

Why source resource bytes were conservatively retained after a write.

PrimitiveMode

glTF primitive topology mode.

Constants

DEFAULT_EXTERNAL_ASSET_DEPTH

Default maximum explicit nested-asset depth for Import::load_asset.

Traits

ResourceResolver

Synchronous resolver for non-data resource URIs.

Functions

import

Opens a glTF or GLB file using the draft validation profile.

import_slice

Parses glTF or GLB bytes using the draft validation profile.

import_slice_with_options

Parses glTF or GLB bytes with explicit loading options.

open

Opens a glTF or GLB file and applies the selected profile’s basic checks.

parse

Parses glTF or GLB bytes and applies the selected profile’s basic checks.

parse_with_options

Parses a container with explicit resource, quota, profile and extension options.

validate

Applies the available checks for the pinned draft profile.
