escolha a pasta de destino

Error message

escolha a pasta de destino

What it means

substack::run validates Options before exporting. If opts.dest, after trimming, is an empty string there is no directory to write the archive into, so it fails fast with 'escolha a pasta de destino' (choose the destination folder).

Solutions

1. Set opts.dest to a valid existing-or-creatable directory path before calling run
2. In the UI, disable the export action until a destination folder is chosen
3. Trim and validate dest in the caller (e.g. show a folder picker) before invoking run

Example fix

// before
let opts = Options { dest: "".into(), ..Default::default() };
substack::run(&opts, progress).await?;
// after
let opts = Options { dest: "/home/user/exports/substack".into(), ..Default::default() };
substack::run(&opts, progress).await?;

let dest = opts.dest.trim();
if dest.is_empty() {
    anyhow::bail!("destination folder required");
}

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

When it happens

Trigger: Calling run(&opts, progress) with opts.dest set to "", whitespace-only, or simply never assigned by the caller/UI.

Common situations: Frontend did not bind the folder-picker result into the options struct; user clicked export before selecting a folder; dest field cleared programmatically.
