Function Documentation

flatten_valid_attribute_chunks()

Array< std::optional< GArray<> > > blender::io::csv::flatten_valid_attribute_chunks ( const Span< ColumnInfo > columns_info, OffsetIndices< int > chunk_offsets, MutableSpan< ChunkResult > chunks )

static

So far, the parsed data is still split into many chunks. This function flattens the chunks into continuous buffers that can be used as attributes.
