Struct LauncherApp 

pub(crate) struct LauncherApp {
    pub(crate) status_msg: String,
    pub(crate) show_kernel_console: bool,
    pub(crate) show_gui_console: bool,
    pub(crate) system: System,
}

Primary state structure for the Launcher GUI application.

Fields

status_msg: String

Human-readable status message displayed in the UI for user feedback.

show_kernel_console: bool

Whether to open a visible console window when spawning the Kernel.

show_gui_console: bool

Whether to open a visible console window when spawning the GUI client.

system: System

System monitor instance used for querying running processes.

Implementations

impl LauncherApp

pub(crate) fn new(_ctx: Context) -> Self

Creates a new LauncherApp instance with default state, initializes the [System] monitor, and resolves the workspace directory.

Arguments

• _ctx - The egui context used for UI rendering and state configuration.

pub(crate) fn draw_kernel_group(&mut self, ui: &mut Ui)

Renders the UI section for configuring and launching the REKTAL Kernel.

Includes a live status indicator (green/red dot), a checkbox for toggling the terminal console, and a button to spawn the process if not already running.

Arguments

• ui - The egui UI builder used to draw the controls.

pub(crate) fn draw_gui_group(&mut self, ui: &mut Ui)

Renders the UI section for configuring and launching the REKTAL GUI client.

Includes a live status indicator (green/red dot), a checkbox for toggling the terminal console, and a button to spawn the process.

Arguments

• ui - The egui UI builder used to draw the controls.

pub(crate) fn is_kernel_active(&self) -> bool

Checks whether a REKTAL Kernel process is currently active on the host system.

Iterates through the active system processes cached in [System] to check if any process name begins with "kernel".

Returns

true if a matching Kernel process is active, false otherwise.

pub(crate) fn is_gui_active(&self) -> bool

Checks whether a REKTAL GUI client process is currently active on the host system.

Iterates through the active system processes cached in [System] to check if any process name begins with "gui".

Returns

true if a matching GUI client process is active, false otherwise.

Trait Implementations

impl App for LauncherApp

fn update(&mut self, ctx: &Context, _frame: &mut Frame)

Primary update function called once per UI frame by eframe.

Renders the central panel with side-by-side controls and live status dots for Kernel and GUI, presents active status messages, refreshes the OS process list, and schedules automatic repaints every 500ms.

fn save(&mut self, _storage: &mut dyn Storage)

Called on shutdown, and perhaps at regular intervals. Allows you to save state.

fn on_exit(&mut self, _gl: Option<&Context>)

Called once on shutdown, after [Self::save].

fn auto_save_interval(&self) -> Duration

Time between automatic calls to [Self::save]

fn clear_color(&self, _visuals: &Visuals) -> [f32; 4]

Background color values for the app, e.g. what is sent to gl.clearColor.

fn persist_egui_memory(&self) -> bool

Controls whether or not the egui memory (window positions etc) will be persisted (only if the “persistence” feature is enabled).

fn raw_input_hook(&mut self, _ctx: &Context, _raw_input: &mut RawInput)

A hook for manipulating or filtering raw input before it is processed by [Self::update].
