Struct AppLayout 

pub struct AppLayout<Node, Message>
where
    Message: Clone,
{
    pub body: Node,
    pub header: Option<Node>,
    pub side_bar: Option<Node>,
    pub footer: Option<Node>,
    pub header_menu: Option<Node>,
    pub context_menu: Option<Node>,
    pub dialog: Option<Dialog<Node, Message>>,
    pub bottom_sheet: Option<BottomSheet<Node, Message>>,
    pub toasts: Vec<Toast<Message>>,
    pub direction: LayoutDirection,
    pub on_close_menus: Option<Message>,
    pub on_close_modals: Option<Message>,
}

The complete declarative description of what should be on screen.

Type parameters:

• Node — the element type your engine consumes. With the snora engine, this is iced::Element<'a, Message>.
• Message — your application’s top-level message type.

Fields are intentionally pub so that direct struct literal syntax is available for advanced callers. The new + chainable setters are the canonical path; direct construction is a power-user escape hatch.

Fields

body: Node

The main content area. Required.

header: Option<Node>

side_bar: Option<Node>

footer: Option<Node>

header_menu: Option<Node>

Optional header-attached dropdown (e.g. File menu’s item list). When Some, the engine installs a transparent backdrop that dispatches Self::on_close_menus on any outside click.

context_menu: Option<Node>

Optional floating context menu (right-click menu). Same backdrop behavior as header_menu.

dialog: Option<Dialog<Node, Message>>

bottom_sheet: Option<BottomSheet<Node, Message>>

toasts: Vec<Toast<Message>>

direction: LayoutDirection

on_close_menus: Option<Message>

Dispatched when the user clicks outside an open menu (header or context). If None, menus still render but the click-outside-to- close backdrop is not installed — the application must then provide explicit close buttons inside its menu content.

on_close_modals: Option<Message>

Dispatched when the user clicks the dim backdrop of a dialog or bottom sheet. Semantics mirror Self::on_close_menus.
