Enum SystemUiMode 

pub enum SystemUiMode {
    EdgeToEdge,
    Immersive,
    ImmersiveSticky,
    LeanBack,
    Manual {
        top: bool,
        bottom: bool,
    },
}

App-facing system-UI (system-bar) override: set_system_ui_mode requests a status-/navigation-bar visibility mode — the Flutter SystemChrome.setEnabledSystemUIMode analog — reaching whichever shell is running the next time it polls (once per frame, mirroring set_app_theme’s delivery timing). See frust_shell_common::system_ui’s module docs for the full layering rationale, the thread contract (a plain Mutex-guarded process-global, callable from any thread), the FFI wire format each mobile shell exports, and where Android/iOS diverge from the five-mode vocabulary.

use frust::{SystemUiMode, set_system_ui_mode};

// Hide all system bars; an edge swipe re-shows them.
set_system_ui_mode(SystemUiMode::Immersive);

The requested system-bar visibility mode (Flutter SystemUiMode parity — see the module docs’ platform-behavior-differences section for where Android/iOS diverge from this vocabulary).

Variants

EdgeToEdge

Default: bars visible, app draws edge-to-edge behind them.

Immersive

Hide all bars; any edge swipe re-shows them (system keeps the gesture).

ImmersiveSticky

Hide all bars; transient overlay on swipe, auto-hides again.

LeanBack

Hide all bars; re-shown by system interactions (tap on Android leanback).

Manual

Show exactly the listed overlays.

Fields

top: bool

Whether the top bar (status bar) is shown.

bottom: bool

Whether the bottom bar (nav bar / home indicator) is shown.
