Module lz4 

Bounded LZ4 block compression for byte columns.

Frames contain a declared total, block size, block count, a length table, and independently compressed blocks. Decoding validates all framing before allocation and each LZ4 block before extending the result.

Structs

Lz4Decoder

Lz4Encoder

Streaming LZ4 encoder. Accumulates data and compresses on finish().

Functions

decode

Decompress LZ4 block-compressed bytes back to raw data.

decode_block

Decompress a single block by index (for random access).

encode

Compress raw bytes using LZ4 block compression.

encode_with_block_size

Compress with a custom block size (useful for testing or tuning).
