Struct LayoutCx 

pub struct LayoutCx<'a, L> { /* private fields */ }

What a layout’s drawing is handed. Same as a page’s, plus the child.

Implementations

impl<L> LayoutCx<'_, L>

pub fn read<R>(&mut self) -> (Rc<R>, Dispatch)

where R: Reducer,

See PageCx::read.

pub fn binding<R>(&self) -> ReducerBinding<R>

where R: Reducer,

See PageCx::binding.

impl<L> LayoutCx<'_, L>

pub fn ui(&mut self) -> &mut Ui

pub fn navigate<R>(&self) -> NavigateHandle<Egui, R>

where R: RouteChain<Egui> + Clone + PartialEq + 'static,

A navigator over the route type the application runs.

pub fn outlet(&self) -> Node

The next segment down the chain, for the layout to draw where it wants.

Handed over rather than drawn here: a layout takes its ui from this same context, so a method that drew the child would need the context twice at once.

pub fn child_is<P: 'static>(&self) -> bool

Whether the segment directly below is P.

What a tab strip needs, and cheaper than it looks: the chain already says which page is mounted, so highlighting the current tab needs neither the route nor a copy of it in state.

Trait Implementations

impl<L> Reads for LayoutCx<'_, L>

fn read<R>(&mut self) -> (Rc<R>, Dispatch)

where R: Reducer + PartialEq,

R as it is now, and what may be asked of the feature that owns it.

fn dispatch<R>(&self) -> Dispatch

where R: Reducer,

What may be asked of the feature that owns R, without reading it: the segment is not drawn again when R changes.
