Struct UsdcFileFormat 

pub struct UsdcFileFormat;

Binary crate format (.usdc) as an sdf::FileFormat, wrapping CrateData and CrateWriter. Also the default writer for the ambiguous .usd extension (C++ USD_WRITE_NEW_USD_FILES_AS_BINARY).

Trait Implementations

impl FileFormat for UsdcFileFormat

fn format_id(&self) -> Token

The format’s stable identifier token (C++ SdfFileFormat::GetFormatId), e.g. "usda".

fn extensions(&self) -> &[&str]

File extensions this format claims, without the leading dot. The first is the canonical one; additional entries (e.g. usdc also claiming usd) let one format be the default for an ambiguous extension.

fn read( &self, resolver: &dyn Resolver, resolved: &ResolvedPath, ) -> Result<LayerData>

Read a layer’s data from resolved, opening the asset (and any sibling assets) through resolver.

fn matches_content(&self, prefix: &[u8]) -> bool

Whether this format can read an asset whose leading bytes are prefix (C++ SdfFileFormat::CanRead). Used to disambiguate an extension claimed by more than one format — binary vs text .usd — by content. The default has no content signature; a binary format overrides it to match its magic.

fn write(&self, data: &dyn AbstractData, sink: &mut dyn WriteSeek) -> Result<()>

Serialize data to sink in this format.

fn caps(&self) -> FileFormatCaps

The operations this format supports (C++ SdfFileFormat’s supportsReading/Writing/Editing plugInfo flags). Defaults to all three; an asymmetric encoding (e.g. an import-only third-party format) overrides this to drop a flag. Layer::export rejects a format lacking WRITE.

fn resolve_layer( &self, _resolver: &dyn Resolver, resolved: &ResolvedPath, ) -> Option<ResolvedPath>

Resolves the real path of the layer to open at resolved — the location it physically loads from and anchors its relative asset paths against (C++ SdfLayer::GetRealPath) — or None if this format cannot read it there.
