Expand description

A data block for variable-width data (e.g. strings, packed rows, etc.)

Fields§

§data: LanceBuffer

The data buffer

§offsets: LanceBuffer

The offsets buffer (contains num_values + 1 offsets)

Offsets MUST start at 0

§bits_per_offset: u8

The number of bits per offset

§num_values: u64

The number of values represented by this block

§block_info: BlockInfo
