Non-owning handle to an RNTupleAttrSetWriter.

RNTupleAttrSetWriter can only be used through an RNTupleAttrSetWriterHandle, a weak_ptr-like object that allows safe access to it. The lifetime of an attribute set writer is tied to its parent RNTupleWriter, so the handle handed out by RNTupleWriter::CreateAttributeSet is invalidated as soon as the parent writer is destructed.
