zip 9.0.0 Rust crate documentation ZipArchive ZipWriter SimpleFileOptions CompressionMethod Deflated features default-features deflate API

💡 Result:

For `zip` **9.0.0**, I couldn’t verify the version-specific docs: the available docs.rs results cover **8.6.0**, not 9.0.0. So treat the API and feature details below as confirmed for 8.6.0, not guaranteed for 9.0.0.

- `ZipArchive` and `ZipWriter` are re-exported at the crate root; `SimpleFileOptions` is in `zip::write`. ([docs.rs](https://docs.rs/zip/latest/zip/?utm_source=openai))
- `CompressionMethod::Deflated` is available when a deflate backend is enabled. The crate’s default features include `deflate`; `default-features = false` disables defaults, so add `features = ["deflate"]` if you want Deflate support explicitly. ([docs.rs](https://docs.rs/zip/latest/zip/enum.CompressionMethod.html?utm_source=openai))
- The documented writer pattern is `SimpleFileOptions::default().compression_method(CompressionMethod::Deflated)`, then `ZipWriter::start_file(...)`. ([docs.rs](https://docs.rs/zip/latest/zip/write/struct.ZipWriter.html?utm_source=openai))

```toml
zip = { version = "9.0.0", default-features = false, features = ["deflate"] }
```

The exact 9.0.0 feature list and declarations remain unverified in the sources available to me.

site:docs.rs/crate/zip/9.0.0 zip 9.0.0 source Cargo.toml features ZipArchive ZipWriter

💡 Result:

The exact `zip` 9.0.0 source page isn’t available in the retrieved results, so I can’t confirm its `Cargo.toml` features or API exports from those results. The available docs.rs result is for **9.0.2**, where the crate re-exports `ZipArchive` and `ZipWriter`; that does not establish their availability in 9.0.0. ([docs.rs](https://docs.rs/crate/zip/latest/source/Cargo.toml?utm_source=openai))

Handle the fallible entry-name API in zip 9.0.0.

ZipFile::name() changed from &str to ZipResult<Cow<'_, str>>. The existing .to_string() call therefore does not compile. Map the name error to RomArchiveError::Malformed and then own the name.

Suggested fix
-        let name = entry.name().to_string();
+        let name = entry
+            .name()
+            .map_err(|e| RomArchiveError::Malformed(e.to_string()))?
+            .into_owned();

Update ZIP entry-name extraction to handle the fallible result from
ZipFile::name, map failures to RomArchiveError::Malformed, and own the
successful name before using it.
