Module compress 

Per-chunk compression with an adaptive “is this worth it?” gate.

Every chunk is compressed independently. That costs a little ratio versus a single solid stream, and buys three things this engine needs: chunks can be processed on any worker in any order, a resumed transfer can skip individual chunks, and one corrupt chunk cannot poison the ones after it.

Structs

Codec

Reusable codec state for one worker.

Encoded

What the encoder decided for one chunk.

FileHint

What we know about a chunk before looking at its bytes.

Enums

Algorithm

Compression algorithm for a chunk payload.

Functions

compress_into

Compress using the calling thread’s Codec.

decompress_into

Decompress using the calling thread’s Codec.

is_incompressible_extension

Does this extension name a format that is already entropy-coded?

with_codec

Run f with the calling thread’s codec.
