Struct AdhocRenderer

pub struct AdhocRenderer<T>
where
    T: Element,
{ /* private fields */ }

Implements a Renderer via a wrapped closure.

Most commonly used to implement a Renderer which does not require its own struct/state.

let renderer = AdhocRenderer::<SomeElement>::new(|segment, context| {
    Ok(vec![
        PlayNote {note: 60, velocity: 100 }
        .over(segment.timing)
    ])
});

Implementations

impl<T> AdhocRenderer<T>

where T: Element,

pub fn new( func: impl Fn(SegmentRef<'_, T>, CompositionContext<'_>) -> Result<Vec<Segment>, RendererError> + 'static, ) -> AdhocRenderer<T>

Creates an AdhocRenderer from a closure.

Trait Implementations

impl<T> Renderer for AdhocRenderer<T>

where T: Element,

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

Renders a Element by calling the AdhocRenderers wrapped closure.

type Element = T

The particular Element this Renderer renders.
