Struct Field 

pub struct Field {
    pub id: ObjectId,
    pub fqn: String,
    pub rect: Option<[f32; 4]>,
    pub is_button: bool,
    pub max_len: Option<usize>,
}

One terminal (leaf) AcroForm field: its object id, fully-qualified name, widget rectangle, and whether it is a checkbox (/FT /Btn).

Fields

id: ObjectId

lopdf object id of the field dictionary.

fqn: String

Fully-qualified, bracketed name (topmostSubform[0].Page1[0]…f1_03[0]).

rect: Option<[f32; 4]>

Widget rectangle [x0, y0, x1, y1] in PDF user space, if present.

is_button: bool

true iff /FT is /Btn (a checkbox/radio).

max_len: Option<usize>

/MaxLen — the cell’s character capacity, when the form declares one (inheritable, like /FT).

The IRS forms set this on their comb cells (the SSN boxes are /MaxLen 9, comb-flagged), and it is the PRIMARY SOURCE for how a value must be formatted: nine characters means nine bare digits, not a hyphenated 123-45-6789, which is eleven and would be silently truncated by the viewer. crate::verify::verify_flat enforces it on read-back, so an over-long write fails closed instead of being quietly mangled.

Implementations

impl Field

pub fn cx(&self) -> Option<f32>

Horizontal center of the widget rectangle.

pub fn cy(&self) -> Option<f32>

Vertical center of the widget rectangle.

Trait Implementations

impl Clone for Field

fn clone(&self) -> Field

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Field

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

Formats the value using the given formatter.
