Struct DisplayPoint 

pub struct DisplayPoint { /* private fields */ }

A visual position: display row + cell column (one cell = one Unicode scalar’s monospace advance; a tab occupies 1..=tab_size cells).

Fields are private and the constructor is pub(crate): no code in the widget crate can fabricate a display point — it must route through TabMap::to_display/TabMap::clip (the crate boundary is the enforcement line). Ordered row-major, so display points compare in visual document order for range and decoration math.

Implementations

impl DisplayPoint

pub fn zero() -> Self

The visual origin, (row 0, col 0).

pub fn row(self) -> DisplayRow

The display row.

pub fn col(self) -> u32

The cell column.
