Struct LoadedImage 

pub struct LoadedImage<'a, Message, Theme, Renderer>
where
    Renderer: Renderer + Renderer,
{
    handle: <Renderer as Renderer>::Handle,
    content: Element<'a, Message, Theme, Renderer>,
}

Forces the wrapped image to be loaded before drawing.

May cause a dropped frame if the image is not already in the cache. This is useful when you want to ensure an image is loaded before it is drawn, for example when swapping out a placeholder. Otherwise, the image may be blank until the next redraw.

Fields

handle: <Renderer as Renderer>::Handle

content: Element<'a, Message, Theme, Renderer>

Implementations

impl<'a, Message, Theme, Renderer> LoadedImage<'a, Message, Theme, Renderer>

where Renderer: Renderer + Renderer, <Renderer as Renderer>::Handle: 'a,

pub(crate) fn new(handle: <Renderer as Renderer>::Handle) -> Self

fn children(&self) -> Vec<Tree>

Returns the state [Tree] of the children of the [Widget].

fn diff(&mut self, tree: &mut Tree)

Reconciles the [Widget] with the provided [Tree].

fn size(&self) -> Size<Length>

fn layout( &mut self, tree: &mut Tree, renderer: &Renderer, limits: &Limits, ) -> Node

Returns the [layout::Node] of the [Widget].

fn operate( &mut self, tree: &mut Tree, layout: Layout<'_>, renderer: &Renderer, operation: &mut dyn Operation, )

Applies an [Operation] to the [Widget].

fn update( &mut self, tree: &mut Tree, event: &Event, layout: Layout<'_>, cursor_position: Cursor, renderer: &Renderer, clipboard: &mut dyn Clipboard, shell: &mut Shell<'_, Message>, viewport: &Rectangle, )
