Enum Value 

pub enum Value<'a> {
    Absent,
    Text(&'a str),
    On(bool),
}

What the field currently holds.

An enum rather than a bag of optional fields, on the same reasoning makeover_layout::Depth is one: a checkbox holding a string is unsayable here, where a struct would let it be said and then have to cope.

Variants

Absent

Nothing yet.

Text(&'a str)

The value of anything that takes typed text, a select included: what a select holds is the value of one of Field::options’s Choices.

It carried the options too until makeover-layout 0.8.0 moved them onto the field, which collapsed a Chosen { options, value } variant into this one. makeover-immediate arrived at the same single-variant shape on its own, from the other direction.

On(bool)

A checkbox, on or off.
