Implementations

impl<S: Hash + Clone> View<S>

pub fn new( key: impl Into<String>, initial_state: S, render_function: impl ViewRenderFunction<S>, ) -> Self

pub fn set_layer(&self, layer: Layer)

Assigns a layer to the view, this will render the view into the layer

pub fn get_layer(&self) -> Option<Layer>

pub fn render(&self, layer: &Layer)

Render the view into the layer

pub fn get_state(&self) -> S

Get the state of the view

pub fn set_state(&self, state: S)

Set the state of the view without rendering the layer

pub fn update_state(&self, state: &S) -> bool

Update the state of the view and render the layer if the state has changed

pub fn contains_point(&self, point: Point) -> bool

pub fn layer_by_key(&self, id: &str) -> Option<Layer>

pub fn viewlayer_node_map_insert(&self, key: impl Into<String>, node: NodeRef)

pub fn set_viewlayer_node_map(&self, cache: HashMap<String, VecDeque<NodeRef>>)

Set the entire viewlayer_node_map cache from a pre-built HashMap Used to inject warm caches created during surface pre-population

pub fn hover_layer(&self, id: &str, location: &Point) -> bool

pub fn add_pre_render_hook<F>(&self, hook: F)

where F: Fn(&S, &View<S>) + Send + Sync + 'static,

Add a pre-render hook that will be called before each render Hook receives: (state, view)

pub fn add_post_render_hook<F>(&self, hook: F)

where F: Fn(&S, &View<S>, &Layer) + Send + Sync + 'static,

Add a post-render hook that will be called after each render Hook receives: (state, view, layer)

pub fn clear_pre_render_hooks(&self)

Clear all pre-render hooks

pub fn clear_post_render_hooks(&self)

Clear all post-render hooks
