Struct Folios 

pub struct Folios {
    pub first: u32,
    pub last: u32,
    pub at: u32,
    pub count: u32,
}

Where one node’s content is set: the folios it runs between, and the pages of the book those folios are.

first and last are what a page has printed on it, which is what a host puts on screen. They are read in reading order rather than compared, so a book whose page counter restarts still opens at first and a node that fits on one page answers with the same folio twice.

at and count are where those pages fall in the book, counting from 0. A page counter that restarts makes them differ from the folios, so they are answered rather than left to arithmetic, and they are the numbers a host fetches the pages by.

Fields

first: u32

The folio the node’s content begins on.

last: u32

The folio it ends on.

at: u32

Which page of the book that first folio is, counting from 0.

count: u32

How many pages the node’s content runs across, so at and count are every page it is on.
