Crate lbzip2 

lbzip2-rs — Pure Rust parallel bzip2 decompressor.

Architecture: 1 reader thread reads ~100 MB of raw compressed bzip2 data into a chunk buffer.

Per chunk the reader does a cheap bit-scan to locate bzip2 block boundaries (magic 0x314159265359 at arbitrary bit offsets), then fans the N sub-ranges out through the shared gatling engine (gatling::gatling_forkjoin::gatling_for_each) — the one constellation worker pool, NOT a private one.

Each worker independently decodes its Burrows-Wheeler blocks and produces decompressed output. Results are reassembled in order and emitted as a streaming Read.

Modules

bitreader

Bit-level reader over a byte slice. Zero-copy — borrows the slice.

block

bzip2 block decoder.

block_scan

Bit-level scanner for bzip2 block boundaries.

bwt

Inverse Burrows-Wheeler Transform.

chunk

Chunk-level parallel bzip2 decoder.

huffman

Canonical Huffman tree decoder for bzip2.

mtf

Move-to-front transform decoder.

parallel

Parallel bzip2 decompression — decode N blocks concurrently.

reader

Streaming parallel bzip2 decompressor implementing Read.

stream

bzip2 stream decoder — sequential multi-block decompression.

Constants

BLOCK_MAGIC

bzip2 block magic: π digits — 0x314159265359 (48 bits, bit-aligned).

FINAL_MAGIC

bzip2 end-of-stream magic: √π digits — 0x177245385090 (48 bits).

Functions

functional_status

Introspection / emit marker — record one functional-status row for the nornir test matrix. Wraps nornir_testmatrix::functional_status behind the testmatrix feature (a compiled-out #[inline] no-op otherwise, with no nornir dep in the default build). Mirrors the korp-collectors reference wiring so nornir test --features testmatrix SEES the lbunzip2 CLI.
