The inputs of zstd_sequences.

Fields

table: &'a [SeqEntry; 2048]

Literal lengths at 0, offsets at 512, match lengths at 1024 (next states absolute).

logs: [u32; 3]

Accuracy logs of the three tables (each at most 9).

bits: &'a [u8]

The sequences bitstream; at least 8 bytes, the last one non-zero.

n: usize

Number of sequences, at least 1.

lits: &'a [u8]

The block’s literals followed by WILD bytes of slack.

out: &'a mut [u8]

The output: decoding writes from start on; the last WILD bytes are slack, so the block may produce out.len() - WILD - start bytes.

start: usize

reps: [u32; 3]

wmax: usize

The largest offset allowed (the window).

hist: usize

History before start that offsets may reach, relative to start (wrapping): an offset must be at most hist + (position - start).
