pub async fn render_over<B: Backend>(
graph: &Graph,
target: &str,
config: RenderConfig,
tier: &Tier<B>,
) -> Result<Render, EngineError>Expand description
target over tier, from the root down: a node memory answers stands as its samples, and
nothing under it is typed, planned or looked up. What the rest computes memory keeps as it
says, offered as nodes where a reader may take them; only persist commits them to a disk.
A failing disk fails no render: memory writes nothing more to it, and the stats say why.
