Download cancelled

Error message

Download cancelled

What it means

download_video checks a cancellation token at the start of each retry attempt and bails with "Download cancelled" if it is already cancelled. This is the cooperative-cancellation path: the user or app requested the download to stop.

Solutions

1. Treat this as an expected control-flow outcome — catch it and surface 'cancelled' to the user, not as a failure.
2. If unintentional, ensure each download gets its own CancellationToken and don't reuse cancelled ones.
3. Check no code path cancels the token prematurely (e.g., timeout wrappers or app-close handlers).

// before starting, ensure the token is fresh
if cancel_token.is_cancelled() {
    cancel_token = CancellationToken::new();
}

match download_video(url, &cancel_token, ...).await {
    Err(e) if e.to_string() == "Download cancelled" => {
        tracing::info!("download cancelled by user"); // not an error for the user
    }
    Err(e) => return Err(e),
    Ok(v) => Ok(v),
}

When it happens

Trigger: Calling download_video with a cancel_token that gets cancelled before or between retry attempts — user pressed stop/cancel, app shutdown, or a stale token reused from a previous cancelled operation.

Common situations: User cancels via UI; app teardown cancels all tokens; caller accidentally shares/reuses a token already cancelled for another download.
