Enum Value 

pub enum Value<'a> {
    Absent,
    Text(&'a str),
    Chosen {
        options: &'a [Choice<'a>],
        value: &'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 select with no options and a checkbox with a string value are both unsayable here, where a struct would let them be said and then have to cope.

Variants

Absent

Nothing yet.

Text(&'a str)

The value of anything that takes typed text.

Chosen

The options of a select, and which of them is current.

Fields

options: &'a [Choice<'a>]

Every option, in the order they are offered.

value: &'a str

The current value. Matched against each option’s value.

On(bool)

A checkbox, on or off.
