Enum PageAtom 

pub enum PageAtom {
    Single(isize),
    Range(isize, isize),
}

One atomic spec inside a PageSelector.

A single index (5, -1) or an inclusive range (2-5, 5--1). Indices are signed so the IM convention -1 = last page, -2 = second-to-last, … can ride through unchanged. Resolution against an actual page count is PageAtom::resolve.

Variants

Single(isize)

Single page index. Negative values count from the end: -1 = last page, -2 = second-to-last, ….

Range(isize, isize)

Inclusive range start..=end. Either endpoint may be negative (5..=-1 = “page 5 through the last page”). After resolution against the actual page count, start <= end is required.
