Struct StructuralMetadataExtension 

pub struct StructuralMetadataExtension;

Property tables, whose columns are buffer views rather than accessors.

Trait Implementations

impl Clone for StructuralMetadataExtension

fn clone(&self) -> StructuralMetadataExtension

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for StructuralMetadataExtension

impl Debug for StructuralMetadataExtension

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for StructuralMetadataExtension

fn default() -> StructuralMetadataExtension

Returns the “default value” for a type.

impl ExtensionHandler for StructuralMetadataExtension

fn name(&self) -> &'static str

Returns the exact glTF extension name handled by this implementation.

fn allows_binary_transform(&self) -> bool

Whether a transform may replace accessor and buffer-view binary data while preserving this extension. Handlers must opt in explicitly after validating their binary-reference semantics.

fn collect_binary_references( &self, document: &Document, _accessors: &mut [bool], buffer_views: &mut [bool], ) -> Result<()>

Marks every accessor and buffer-view reference owned by this extension.

fn remap_binary_references( &self, document: &mut Document, _accessors: &[Option<usize>], buffer_views: &[Option<usize>], ) -> Result<()>

Applies the maps produced by binary compaction to references owned by this extension. This is called only for handlers that explicitly allow binary transforms.

fn validate( &self, _document: &Document, _context: &mut ExtensionValidationContext, ) -> Result<()>

Performs extension-specific strict validation and records narrowly scoped core-validation exemptions in context.

fn decode_primitive( &self, _document: &Document, _resources: &ResourceStore, _primitive: PrimitiveRef<'_>, ) -> Option<Result<Mesh>>

Decodes geometry for primitive, or returns None when this handler does not own that primitive.
