escolha a pasta de destino

Error message

escolha a pasta de destino

What it means

Thrown at the top of the Goodreads export tool's run() when the required destination folder option is blank or whitespace-only. The tool needs a directory where it writes goodreads_library_export.csv and generated output files, so it refuses to run without one.

Solutions

1. Set opts.dest to an existing or creatable directory path before calling run.
2. Validate the destination field in your UI/config layer and require a non-empty value.
3. Trim user input and store the trimmed path in Options.

Example fix

// before
let opts = Options { dest: cfg.dest, .. };
// after
let dest = cfg.dest.trim();
if dest.is_empty() { return Err(anyhow!("escolha a pasta de destino")); }
let opts = Options { dest: dest.to_string(), .. };

if opts.dest.trim().is_empty() {
    return Err(anyhow!("dest é obrigatório: informe a pasta de saída"));
}
std::fs::create_dir_all(opts.dest.trim())?;

fn has_dest(opts: &Options) -> bool {
    !opts.dest.trim().is_empty()
}

match run(&opts, &p).await {
    Err(e) if e.to_string().contains("pasta de destino") => eprintln!("selecione uma pasta de destino antes de exportar"),
    other => other?,
}

When it happens

Trigger: Calling run(&opts, p) where opts.dest is "" or contains only whitespace (opts.dest.trim().is_empty()).

Common situations: UI form left empty before invoking the tool; config file missing the dest key so the default empty string is used; trailing-space-only input that survives validation.
