pub(super) fn frame_sections(
mesh: &[u8],
vertex: &[u8],
index: &[u8],
) -> Result<Bytes, ParquetError>Expand description
Assemble the three Parquet buffers into the length-prefixed section layout shared by the whole-model serializer and the incremental cache writer. Section lengths are u32 on the wire; fail loud instead of truncating a section over 4 GiB into a silently corrupt blob.
