Enum Underline 

pub enum Underline {
    None,
    Single,
    Double,
    Dotted,
    Wavy,
}

A line under a run.

An enum rather than a bool because every toolkit distinguishes at least single from double, and because a wavy underline is how an app draws its diagnostics (a spelling or grammar mark of its own making) without fighting the platform’s checker for the same pixels.

Variants

None

Single

Double

Dotted

Wavy

The squiggle. A backend with no wavy style draws Single.
