doc_bit_width: u8

Bit width for doc deltas (always 0, 8, 16, or 32)

term_freqs: Vec<u8>

Term frequencies (rounded bitpacked: 8/16/32 bits)

tf_bit_width: u8

Bit width for term frequencies (always 0, 8, 16, or 32)

first_doc_id: u32

First doc_id in this block (absolute)

last_doc_id: u32

Last doc_id in this block (absolute)

num_docs: u16

Number of docs in this block

max_tf: u32

Maximum term frequency in this block

max_block_score: f32

Maximum impact score in this block (for MaxScore/WAND)
