pub fn compose(
template: &Template,
answers: &Answers,
catalog: &Catalog,
with: &Fill,
) -> Result<Plan, ComposeError>Expand description
The game template makes for answers (each question they leave out
at its default), with the engine’s modules in catalog and the
placeholders filled with: its files and their bytes, and what its
parts turn on. The same input always gives the same plan.
