Struct DisplayRow 

pub struct DisplayRow(/* private fields */);

A display row, 0-based. In the tab-only map: DisplayRow(r) ⇔ buffer row r.

A distinct newtype because the FoldMap layer breaks that 1:1 — a folded row hides buffer rows beneath it — so every site that would otherwise assume display row equals buffer row is a compile error to revisit. The field is pub(crate): consumer crates can read a display row (DisplayRow::index) but can never mint one from arithmetic — every display row in existence came out of a FoldMap/TabMap method, so “anchor something at a buffer row × line height” is a compile error rather than something to catch by eye. This keeps popups and other row-anchored chrome correctly offset when a fold sits above them.

Implementations

impl DisplayRow

pub const fn index(self) -> u32

The 0-based row index — read-only; pair with the pixel projection’s one row → y map, never with hand arithmetic.
