Struct ShellContext 

pub struct ShellContext {
    pub layout: Signal<ShellLayout>,
    pub breakpoint: ReadSignal<ShellBreakpoint>,
    pub sidebar_visible: Signal<bool>,
    pub sidebar_mobile_open: Signal<bool>,
    pub mobile_sidebar: ReadSignal<MobileSidebar>,
    pub desktop_sidebar: ReadSignal<DesktopSidebar>,

    pub modal_open: Signal<bool>,
    pub search_active: Signal<bool>,
    pub sheet_snap: Signal<SheetSnap>,
    /* private fields */
}

Reactive context shared across the shell tree.

Provided by AppShell via use_context_provider. Access it from any descendant component with use_shell_context.

Fields

layout: Signal<ShellLayout>

Current layout mode, reactive via Signal.

breakpoint: ReadSignal<ShellBreakpoint>

Current viewport breakpoint, read-only reactive signal.

sidebar_visible: Signal<bool>

Whether the desktop sidebar is in its expanded state (true) or not (false).

For Full: true = visible at full width, false = collapsed to zero. For Expandable: true = full width, false = rail width. For Rail: ignored (rail is always visible at its fixed width).

sidebar_mobile_open: Signal<bool>

Whether the mobile overlay sidebar is open.

mobile_sidebar: ReadSignal<MobileSidebar>

Mobile sidebar variant (Drawer, Rail, or Hidden).

desktop_sidebar: ReadSignal<DesktopSidebar>

Desktop sidebar variant (Full, Rail, or Expandable).

stack_depth: Signal<u32>

Stack navigation depth. Starts at 1 (root screen).

modal_open: Signal<bool>

Whether the full-screen modal is currently presented.

search_active: Signal<bool>

Whether the search overlay is currently active.

sheet_snap: Signal<SheetSnap>

Current snap position of the persistent bottom sheet.

Implementations

impl ShellContext

pub fn is_mobile(&self) -> bool

true when the current breakpoint is compact (phone-sized viewport).

pub fn toggle_sidebar(&self)

Toggles the appropriate sidebar state based on the current breakpoint.

• On mobile: toggles sidebar_mobile_open (overlay open/closed)
• On desktop Full / Expandable: toggles sidebar_visible
• On desktop Rail: no-op (rail is always visible)

Takes &self because Signal has interior mutability.

pub fn sidebar_state(&self) -> &'static str

Returns the data-shell-sidebar-state attribute value for the root element.

Context	Value
Mobile open	"open"
Mobile closed	"closed"
Desktop expanded	"expanded"
Desktop Full collapsed	"collapsed"
Desktop Rail (always)	"rail"
Desktop Expandable collapsed	"rail"

pub fn push_stack(&self)

Pushes a new screen onto the stack (increments depth by 1).

pub fn pop_stack(&self)

Pops the top screen from the stack (decrements depth by 1, minimum 1).

pub fn reset_stack(&self)

Resets the stack to the root screen (depth 1).

pub fn can_go_back(&self) -> bool

true when there is at least one screen above the root to pop back to.

pub fn open_modal(&self)

Presents the full-screen modal.

pub fn close_modal(&self)

Dismisses the full-screen modal.

pub fn toggle_modal(&self)

Toggles the full-screen modal between presented and dismissed.

pub fn open_search(&self)

Activates the search overlay.

pub fn close_search(&self)

Deactivates the search overlay.

pub fn toggle_search(&self)

Toggles the search overlay between active and inactive.

pub fn set_sheet_snap(&self, snap: SheetSnap)

Sets the bottom sheet to the given snap position.

Trait Implementations

impl Clone for ShellContext

fn clone(&self) -> ShellContext

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
