pub fn extract_cell_bytes(
tile: &SparseTile,
coord: &[CoordValue],
) -> ArrayResult<Option<Vec<u8>>>Expand description
Extract the encoded CellPayload bytes for a specific coord from a
SparseTile.
Returns None when the coord is not present in the tile. Encodes the
matched row’s attrs + valid-time bounds back into the CellPayload wire
format so the bytes can be fed directly to
crate::query::ceiling::ceiling_resolve_cell.
The returned Vec<u8> is always freshly allocated (no lifetime coupling to
the tile).
