escolha a pasta de destino

Error message

escolha a pasta de destino

What it means

The TikTok sound downloader (sound::run) refuses to start when opts.dest is empty or whitespace-only. The destination folder is required because every extracted audio file is written under it (create_dir_all is called immediately after the check). The library throws this early, before any network work, so users get an immediate actionable message instead of a late IO failure.

Solutions

Set opts.dest to a valid directory path before calling run()
Validate that dest.trim() is non-empty in the caller/UI before invoking run()
Fall back to a sensible default directory (e.g. downloads dir) when the user has not chosen one

Example fix

// before
let opts = Options { dest: String::new(), ..Default::default() };
run(&opts, progress).await?;
// after
let opts = Options { dest: chosen_dir.unwrap_or_else(default_downloads_dir), ..Default::default() };
assert!(!opts.dest.trim().is_empty());
run(&opts, progress).await?;

Defensive patterns

Strategy: validation

Validate before calling

if opts.dest.trim().is_empty() {
    return Err(anyhow!("dest é obrigatório: escolha a pasta de destino antes de chamar run()"));
}

Prevention

Always populate dest from a folder picker with a non-empty default
Validate all mandatory Options fields in a shared constructor

When it happens

Trigger: Calling run() with Options whose dest field is "", " " or otherwise trims to empty; typically when the caller constructs Options programmatically without a folder or the UI passed no destination selection.

Common situations: Desktop/Tauri app user clicks download without picking a folder; config file or CLI argument missing --dest; a wrapper script builds Options with default empty strings for optional fields but dest is actually mandatory.
