não foi possível abrir o zip

Error message

não foi possível abrir o zip: {}

What it means

The path was a .zip but zip::ZipArchive::new failed, so the archive cannot be opened or indexed. The underlying zip error is embedded in the message (e.g. invalid archive, unsupported compression, I/O error).

Solutions

  1. Read the embedded {} detail to identify the specific zip error
  2. Re-download the GDPR export from Reddit and verify the file size/checksum
  3. Open the zip with `unzip -t file.zip` to confirm integrity
  4. Ensure the file is not 0 bytes or an HTML page (`file export.zip`)

Example fix

// before
path: "export.zip"  // 0-byte truncated download
// after
# re-download, verify, then
path: "export.zip"  # valid, unzip -t passes
Defensive patterns

Strategy: validation

Validate before calling

fn zip_is_valid(path: &str) -> bool {
    std::fs::File::open(path)
        .map(|f| zip::ZipArchive::new(f).is_ok())
        .unwrap_or(false)
}
// assert!(zip_is_valid("export.zip"), "corrupt or truncated zip");

Try / catch

match run(opts).await {
    Err(e) if e.to_string().starts_with("não foi possível abrir o zip") => {
        // surface the embedded zip error; prompt user to re-download the export
    }
    other => other?,
}

Prevention

When it happens

Trigger: File::open succeeded but the bytes are not a valid zip: truncated/corrupt download, HTML error page saved as .zip, unsupported zip variant, or empty file.

Common situations: Interrupted download of the export; browser saved a login/error page with a .zip name; disk full or antivirus quarantining content; wrong file renamed to .zip.
