Enum Value 

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

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.

The options are the field’s and never this type’s, which is what keeps a Chosen { options, value } variant from existing. makeover-immediate carries the same single-variant shape.

On(bool)

A checkbox, on or off.

Between

Both ends of a FieldKind::Interval, lower first.

Two values rather than one string with a separator, for makeover_layout::Field::upper_name’s reason one level down: an interval submits under two names, so it comes back as two values, and a delimiter this crate owned could appear inside either of them.

Either end may be empty while the other stands. “Over 120 BPM” is a lower end and no upper one, and it is an answer rather than a half-filled form.

Fields

lower: &'a str

What the lower box holds now.

upper: &'a str

What the upper box holds now.
