Enum Progression 

pub enum Progression {
    RightToLeft,
    LeftToRight,
}

Which way successive columns advance. This is a property of the script, not of “vertical text”: CJK columns advance right-to-left, traditional Mongolian advances left-to-right. Hosts must read it from the Layout rather than assuming a direction.

Variants

RightToLeft

vertical-rl: columns[0] is the rightmost column (CJK).

LeftToRight

vertical-lr: columns[0] is the leftmost column (Mongolian).
