Overview

One row's span, measured on both axes.

Both counts cover only the row's visible content: whitespace absorbed at a soft wrap, and the newline ending a hard one, belong to no row. So the next row's start may sit past this row's start + length, and an index in that gap resolves to the earlier row (see #row_at).

Constant Summary collapse

EMPTY =

A zero-length row; EMPTY.with(start: n) rebases it onto an index.

Returns:

new(start: 0, length: 0, columns: 0)
