Struct WalkerStatus 

pub(crate) struct WalkerStatus {
    pub(crate) plugin_dirs: Arc<Mutex<Vec<String>>>,
    pub(crate) audio_dirs: Arc<Mutex<Vec<String>>>,
    pub(crate) daw_dirs: Arc<Mutex<Vec<String>>>,
    pub(crate) preset_dirs: Arc<Mutex<Vec<String>>>,
    pub(crate) midi_dirs: Arc<Mutex<Vec<String>>>,
    pub(crate) pdf_dirs: Arc<Mutex<Vec<String>>>,
    pub(crate) unified_scanning: AtomicBool,
}

Tracks active directory paths being walked by each scanner for live status display.

Fields

plugin_dirs: Arc<Mutex<Vec<String>>>

audio_dirs: Arc<Mutex<Vec<String>>>

daw_dirs: Arc<Mutex<Vec<String>>>

preset_dirs: Arc<Mutex<Vec<String>>>

midi_dirs: Arc<Mutex<Vec<String>>>

pdf_dirs: Arc<Mutex<Vec<String>>>

unified_scanning: AtomicBool

True while scan_unified is active. Frontend walker-status tiles collapse 4 → 1 display when this is true (the single walker fans its dir-push out to all 4 *_dirs lists; showing all 4 would be redundant).
