Struct RasterFacet

pub struct RasterFacet { /* private fields */ }

Expand description

A facet constructed with a raster, style and size.

Implementations§

impl RasterFacet

pub fn new(raster: Raster, style: Style, size: Size) -> Self

Construct a facet with a raster, style and size.

Trait Implementations§

fn update_layers( &mut self, _size: Size, layer_group: &mut dyn LayerGroup, _render_context: &mut RenderContext, _view_context: &ViewAssistantContext, ) -> Result<(), Error>

Called by the scene on facets when it is time for them to update their contents. Facets can add, remove or change layers in the layer group. Those layers will be combined with all the other facet layers in the scene and added to a render composition for display.

fn calculate_size(&self, _available: Size) -> Size

Should return the current size needed by this facet.

fn associate_facet_id(&mut self, facet_id: FacetId)

Optional method for facets that wish to send themselves messages using an AppSender that they were passed during creation.

fn handle_message(&mut self, msg: Box<dyn Any>)

Method for receiving arbitrary message, like SetColorMessage or SetTextMessage.
