Failed to flush file {}: {}

Error message

Failed to flush file {}: {}

What it means

After the stream ends, the engine flushes the 8 MB BufWriter; if that final flush fails this error is raised and the download is treated as failed even though all bytes were received. The model status resets to Missing so the retry path works.

Solutions

1. Free disk space and retry — the partial file resumes from its flushed offset
2. Exclude the models directory from sync/antivirus tools and retry
3. If the models dir lives on external storage, verify it is still mounted before retrying
4. Flush periodically or shrink the buffer so failures surface earlier with less data at risk

match result {
    Err(e) if e.to_string().starts_with("Failed to flush file") => {
        // All bytes arrived but the last buffer write failed: check disk space/AV, then retry (resumes)
        check_free_space(); retry_download_with_resume()
    }
    other => other,
}

When it happens

Trigger: Disk fills exactly as the last buffered bytes are flushed; the target file is deleted or its permissions change during the download; removable storage ejected before completion; OS write-cache failure.

Common situations: Earlier chunks consumed the remaining space so the final 8 MB flush fails; antivirus quarantining the file at completion; user unmounting an external models drive mid-download.
