Struct Section 

struct Section {
    module: &'static str,
    trait_name: &'static str,
    heading: &'static str,
    lead: &'static str,
}

One section of the page: a facade module, the trait its entries implement, and the prose that introduces them.

Fields

module: &'static str

The facade module, e.g. sampler — also the atune::… path a reader uses.

trait_name: &'static str

The trait an entry must implement to belong in this section.

heading: &'static str

The section’s heading.

lead: &'static str

One sentence of framing, so a table never stands alone.
