Enum PostingCodec 

pub enum PostingCodec {
    Rounded = 0,
    Packed = 1,
    Pfor = 2,
}

Encoding of the packed arrays inside one posting block.

Variants

Rounded = 0

Widths rounded up to 0/8/16/32 bits; decodes with plain SIMD widening. This is the low-overhead performance baseline.

Packed = 1

Exact bit widths (BP128 style): ~1.8× smaller than Rounded on the repository benchmark for ~10 % slower decoding.

Pfor = 2

Exact width with up to 10 % patched exceptions (OptP4D style): smallest, ~30 % slower decoding than Rounded.
