Enum ButtonKind 

pub enum ButtonKind {
    Checkbox,
    Radio,
    PushButton,
}

Sub-kind of a button field.

AcroForm models all of checkbox, radio button, and push button as the same /Btn field type, distinguished only by the Pushbutton and Radio flags in the field flags word. Use button_kind to derive this enum from a FieldFlags value.

Variants

Checkbox

Two-state toggle. Default kind when neither Pushbutton nor Radio flags are set. Drawn as a tickbox; user clicks to flip its value between the off-state and an “on” appearance state.

Radio

Mutually-exclusive option within a parent radio group. Selecting one radio child automatically de-selects its siblings — see select_radio.

PushButton

Click-to-action button without persistent state. Typically wired to a JavaScript or submit/reset action via the /AA dictionary; its value is not meaningful as form data.

Trait Implementations

impl Clone for ButtonKind

fn clone(&self) -> ButtonKind

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ButtonKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ButtonKind

fn eq(&self, other: &ButtonKind) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
