Struct Rule 

pub struct Rule { /* private fields */ }

A rule across the whole width, drawn with ─, or - for BoxChars::Ascii.

A title sits at the left:

── Title ──────────────

A rule fills any width it is given. It measures 1 cell wide without a title. With one it measures the 4-cell margin plus the title.

The title counts as one cell at the narrowest, since a title that does not fit ends in …. At the widest it counts as its widest line. Only the first non-empty line of a multi-line title is drawn.
