Struct DesktopHost 

pub struct DesktopHost<T: Transport> { /* private fields */ }

A desktop host facade: many panes/windows over one Session.

The desktop reuses one session for every open pane, so panes that share a resource stay coherent for free: an edit submitted on one pane fans out through Session::pump to every pane subscribed to the same resource.

Implementations

impl<T: Transport> DesktopHost<T>

pub fn new(transport: T) -> Self

Starts a desktop host over transport, adopting the desktop preset.

pub fn open_pane( &mut self, cx: &mut Cx, registry: &LensRegistry, pane: Symbol, resource: Symbol, ) -> Result<Expr>

Opens resource into the named pane with the universal lenses, tracks the pane, and returns its initial Scene.

Opening the same resource into several panes subscribes each of them; re-opening an already-tracked pane re-subscribes it without duplicating it in DesktopHost::panes.

pub fn submit( &mut self, cx: &mut Cx, registry: &LensRegistry, pane: &Symbol, intent: Expr, ) -> Result<Vec<SceneUpdate>>

Submits an Intent against pane and pumps.

The returned updates may span several panes when they share the edited resource.

pub fn panes(&self) -> Vec<Symbol>

The panes currently open, in the order they were first opened.

pub fn caps(&self) -> &SurfaceCaps

The desktop’s advertised surface capabilities (the desktop preset).

pub fn transport_mut(&mut self) -> &mut T

Mutable access to the underlying transport, e.g. to drive reconnection.
