Struct DocumentAccessorSource 

pub struct DocumentAccessorSource<'a> { /* private fields */ }

Accessor source backed by a Document and its resolved resources.

Implementations

impl<'a> DocumentAccessorSource<'a>

pub fn new(document: &'a Document, resources: &'a ResourceStore) -> Self

Creates an accessor source over a document and resolved buffers.

pub fn read_buffer_view(&self, index: usize) -> Result<Vec<u8>>

Copies one complete buffer view from the resolved resource store.

The returned bytes retain the buffer view’s original layout, including accessor stride or padding. Use Self::read_accessor when a tightly packed, sparse-materialized accessor payload is needed.

pub fn read_accessor(&self, index: usize) -> Result<AccessorData>

Reads and materializes one accessor by zero-based index.

Trait Implementations

impl AccessorSource for DocumentAccessorSource<'_>

fn read_attribute( &self, index: usize, expected: &[&str], allowed: &[u32], ) -> Result<DecodedAccessor, GltfError>

Reads one attribute accessor, validating its glTF type against expected_types (e.g. ["VEC3"]) and component type against allowed_component_types (glTF component-type constants).

fn read_indices(&self, index: usize) -> Result<Vec<u32>, GltfError>

Reads a SCALAR index accessor as u32 values.
