escolha a pasta de destino

Error message

escolha a pasta de destino

What it means

tiktok::download::run validates opts.dest before doing any work; if the destination folder string is empty or whitespace it throws "escolha a pasta de destino" (choose the destination folder). It is a required-argument guard executed before create_dir_all.

Solutions

  1. Set opts.dest to a valid existing/writable directory path before calling run
  2. In UI code, disable the download action until a destination is selected
  3. Validate dest non-empty and writable at the caller boundary

Example fix

// before
let opts = Options { dest: "".into(), .. };
run(&opts).await?;
// after
let opts = Options { dest: "/home/user/Downloads/tiktok".into(), .. };
std::fs::create_dir_all(&opts.dest)?;
run(&opts).await?;
Defensive patterns

Strategy: validation

Validate before calling

if opts.dest.trim().is_empty() { return Err("destination folder required"); }
let dest = std::path::Path::new(opts.dest.trim());
std::fs::create_dir_all(dest)?;

Try / catch

match run(&opts, progress).await {
    Err(e) if e.to_string().contains("escolha a pasta de destino") => {
        // prompt user to pick a folder, then retry
    }
    other => other,
}

Prevention

When it happens

Trigger: Calling run with Options.dest = "" or containing only whitespace — omitted field in the UI/CLI, default struct not filled, or the frontend sending an empty string.

Common situations: User hasn't picked a download folder yet; a settings reset cleared the saved destination; a binding bug where the folder picker result never reaches opts.dest.
