rustfs-zip has one workspace consumer, and it uses only
CompressionFormat::{from_extension, extension, get_decoder} and
ArchiveLimits. Remove the tar/zip extract, zip create, and in-memory
compress helpers together with the types and dependencies that only
served them. Trimming public API is semver-major once the stable tag is
cut, so it costs least now.

## 📖 Overview
|
|
|
|
**RustFS Zip** provides the archive primitives used by the [RustFS](https://rustfs.com) archive extract flow:
|
|
|
|
- identify a compression format from an archive extension
|
|
- wrap an async reader in the matching stream decoder
|
|
- carry the shared default archive guardrails
|
|
|
|
## Current Features
|
|
|
|
- `CompressionFormat::from_extension()` for extension-based format detection, including tar-family suffixes such as `tgz`, `tbz2`, `txz`, and `tzst`
|
|
- `CompressionFormat::get_decoder()` for async stream decoding of `gzip`, `bzip2`, `zlib`, `xz`, and `zstd`, plus a pass-through reader for plain `tar`
|
|
- `ArchiveLimits` with the default entry count, entry size, total unpacked size, and path length guardrails
|
|
|
|
## Current Boundaries
|
|
|
|
- ZIP has no stream decoder: `get_decoder()` rejects `CompressionFormat::Zip`, because ZIP needs central-directory semantics that a forward-only stream cannot provide
|
|
- This crate detects formats and hands back decoders; archive iteration, entry writing, and extraction to disk belong to the caller
|
|
- `ArchiveLimits` carries the values only; enforcement and the resulting protocol error belong to the caller
|
|
- Archive extraction safety policy remains the responsibility of the RustFS caller for object-store flows
