Struct lay_rs::view::View

pub struct View<S: Hash + Clone> {
    pub layer: Arc<RwLock<Option<Layer>>>,
    /* private fields */
}

A View<S> is a struct to support the creation of complex hierarchies of layers that can be rendered by the engine.

Fields

layer: Arc<RwLock<Option<Layer>>>

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 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 get_internal_state<T: Clone + 'static>( &self, name: impl AsRef<str>, ) -> Option<T>

pub fn set_internal_state<T: Clone + Send + Sync + 'static>( &self, name: impl AsRef<str>, val: &T, )

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

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