Module system_audio 

SystemAudioRow + SystemAudioAppList (M-UI.9 / AUT-129) — the tray popover’s system-audio section. Collapsed = one row showing the currently-selected count + overlapping app icons + toggle. Expanded = a filter row (All / None / Suggested) + per-app rows with selection checkboxes + live meters.

Stateless: selection set is a prop. Callbacks would land in app-ui per the presentational contract.

Structs

AppIconView

View-model for one app icon — used both in the collapsed stack and inside expanded AudioAppRows.

AudioAppView

One app row inside the expanded list.

SystemAudioAppListProps

Props for the SystemAudioAppList component.

SystemAudioRowProps

Props for the SystemAudioRow component.

SystemAudioView

View-model for the collapsed SystemAudioRow.

Enums

AudioFilter

Constants

ICON_STACK_MAX

Maximum visible icons before the stack collapses to an overflow pill. Module-level so tests + downstream consumers can read it without a Leptos-component receiver (components are functions, not types — impl Component {} won’t compile).

ICON_STACK_MAX_VISIBLE 🔒

Functions

SystemAudioAppList

Expanded list — filter row + per-app rows.

SystemAudioRow

Collapsed system-audio row.

build_icon_stack 🔒

Stack at most ICON_STACK_MAX_VISIBLE icons + an overflow pill for the rest.

format_selection_count

Format "N of M apps" (plural-aware).

render_app_row 🔒
