fn as_any(&self) -> &dyn Any
fn as_any_arc(self: Arc<Self>) -> Arc<dyn Any + Send + Sync>
fn to_layout(&self) -> LayoutRef
Sourcefn encoding(&self) -> LayoutEncodingRef
fn encoding(&self) -> LayoutEncodingRef
Returns the crate::LayoutEncoding for this layout.
Sourcefn child(&self, idx: usize) -> VortexResult<LayoutRef>
fn child(&self, idx: usize) -> VortexResult<LayoutRef>
Get the child at the given index.
Sourcefn child_type(&self, idx: usize) -> LayoutChildType
fn child_type(&self, idx: usize) -> LayoutChildType
