Struct RendererGroup

pub struct RendererGroup<T> {
    pub renderers: Vec<Box<dyn Renderer<Element = T>>>,
}

A group of Renderers for a single Renderer::Element. This group is itself a Renderer which renders as a unit, returning crate::error::RendererError if any of its Renderers do.

Fields

renderers: Vec<Box<dyn Renderer<Element = T>>>

The renderers of this group.

Implementations

impl<T> RendererGroup<T>

pub fn new() -> RendererGroup<T>

Creates an empty RendererGroup.

Trait Implementations

impl<T, R> Add<R> for RendererGroup<T>

where R: Renderer<Element = T> + 'static,

type Output = RendererGroup<T>

The resulting type after applying the + operator.

fn add(self, rhs: R) -> <RendererGroup<T> as Add<R>>::Output

Performs the + operation.

impl<T> Default for RendererGroup<T>

fn default() -> RendererGroup<T>

Returns the “default value” for a type.

impl<T> Renderer for RendererGroup<T>

where T: Element,

type Element = T

The particular Element this Renderer renders.

fn render( &self, segment: SegmentRef<'_, <RendererGroup<T> as Renderer>::Element>, context: CompositionContext<'_>, ) -> Result<Vec<Segment>, RendererError>

Renderers a SegmentRef<Self::Element> with CompositionContext, returning additional Segments as children.
