Error message

not all segments completed

What it means

After all worker tasks finish, download_chunked locks the segment table and verifies every segment's state flag equals SEG_DONE. If any segment is still pending/failed/in-progress, the part file is not complete and the library refuses to proceed to assembly. This is a post-join completeness invariant for the multi-segment download.

Solutions

1. Inspect the segment states logged before this error to find which segment(s) did not reach SEG_DONE and why.
2. Check whether first_err from worker failures was consumed earlier; make sure a failed segment always surfaces its error.
3. Delete the stale .part file and retry the download so all segments start fresh.
4. Fix the state machine so every worker exit path (success, failure, cancel) deterministically sets a terminal segment state.

// caller pattern
if let Err(e) = download(...).await {
    if e.to_string().contains("not all segments completed") {
        fs::remove_file(&part_path).ok(); // discard partial state, retry clean
    }
}

When it happens

Trigger: Worker exits without marking its segment SEG_DONE: a segment failed and the error was recorded but first_err was somehow not propagated, a worker was aborted early (cancel path), or retry bookkeeping reset a segment state after its worker ended.

Common situations: Cancellations racing with completion, a worker that hit a fatal error which panicking tasks masked, or state-machine bugs where a segment stays in SEG_FAILED after exhausting retries while other workers finish normally.

Understand the failure class

Background: "Invalid state transition" errors: "status must be X, actually Y", "already rejected/charging/uninstalled", "cannot ... while running" — what they mean when a library rejects your call — this error's family across 31 libraries.
