Enum FieldKindSpec 

#[non_exhaustive]
pub enum FieldKindSpec {
    Text,
    Check {
        on: String,
    },
    Radio {
        buttons: Vec<(Rect, String)>,
    },
}

Which kind of control a created field is.

Scoped to the three kinds a document author reaches for first. A combo box, list box or signature field is a larger surface — /Opt ordering and selection semantics for the first two, a byte-range placeholder and a certificate for the third — and is deliberately not offered here rather than offered half-built.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Text

A single-line text field (/Tx).

Check

A check box (/Btn with neither the push-button nor the radio bit).

The string is the name of the on state — what /V and /AS hold when the box is ticked, and the key the on appearance is filed under. Yes is the conventional choice; the off state is always Off.

Fields

on: String

The on-state name.

Radio

A radio group (/Btn with bit 16 set).

One button per entry: each is a widget on its own rectangle, and the string is that button’s export value — the name /V takes when that button is the one chosen.

Fields

buttons: Vec<(Rect, String)>

Each button’s rectangle and export value, in order.
