# version-rust

Rust rewrite of `version-python` (same repo, `main` branch still carries the
flat python layout). Goal: one concise binary + webapp, eventually replacing
the python tooling.

## Why this structure

- `main` stays untouched (flat python layout) until the rewrite reaches parity.
- This branch re-homes the python code into `version-python/` (via `git mv`,
  history preserved) and starts `version-rust/` beside it.
- `version-python/AGENTS.md` still documents the python stage — its rules
  (secrets, failure policy, idempotency, rate limiting) apply to the rewrite
  too and are the contract the Rust version must keep.

## Planned crate choices (initial, adjust as modules get ported)

| Concern | Python today | Rust plan |
|---|---|---|
| 7z extraction (extract_all) | 7z CLI, cp437 name repair, /var/tmp fallback | `sevenz-rust2` (pure Rust, LZMA2/PPMD/AES-256); zip via `zip` crate; rar likely still needs an external tool |
| HTTP client | `requests` | `reqwest` (blocking first, async where the webapp needs it) |
| sha256 (gofile website token, --hash manifest) | hashlib | `sha2` |
| Fuzzy matching (sorter) | difflib-style ratios | `strsim` — port thresholds exactly, add unit tests |
| CLI | argparse | `clap` |
| Webapp | — | `axum` (CLI parity first, webapp second) |
| Discord export | DCE docker container (external) | unchanged: shell out to docker |

## Port order (suggested)

1. `state` / `globalstore` — state.json + urls.json schemas must stay
   backward compatible with the python versions.
2. hosters: `gofile` (one guest account per run!), `zero807` (UA + Referer).
3. extraction + manifest appender.
4. catalogue / sorter (hardest logic; port the matching rules documented in
   `version-python/AGENTS.md` §7 with tests).
5. webapp on top.
