Trait Renderer

pub trait Renderer {
    type Element: Element;

    // Required method
    fn render(
        &self,
        segment: SegmentRef<'_, Self::Element>,
        context: CompositionContext<'_>,
    ) -> Result<Vec<Segment>, RendererError>;
}

Defines render behavior for a specific Element.

Every render operation during composition receives a SegmentRef<Self::Element> with CompositionContext and may return Vec<Segment> on success, or RendererError::MissingContext in the case that its render dependencies are not satisfied (which will be retried later).

Required Associated Types

type Element: Element

The particular Element this Renderer renders.

Required Methods

fn render( &self, segment: SegmentRef<'_, Self::Element>, context: CompositionContext<'_>, ) -> Result<Vec<Segment>, RendererError>

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