Struct PdfArray 

pub struct PdfArray(pub Vec<PdfObject>);

PDF Array object - Ordered collection of PDF objects.

Arrays can contain any PDF object type, including other arrays and dictionaries. They are written in PDF syntax as [item1 item2 ... itemN].

Common Uses

• Rectangle specifications: [llx lly urx ury]
• Color values: [r g b]
• Matrix transformations: [a b c d e f]
• Resource lists

Example

use oxidize_pdf::parser::objects::{PdfArray, PdfObject};

// Create a MediaBox array [0 0 612 792]
let mut media_box = PdfArray::new();
media_box.push(PdfObject::Integer(0));
media_box.push(PdfObject::Integer(0));
media_box.push(PdfObject::Integer(612));
media_box.push(PdfObject::Integer(792));

assert_eq!(media_box.len(), 4);

Tuple Fields

0: Vec<PdfObject>

Implementations

impl PdfArray

pub fn new() -> Self

Create a new empty array

pub fn len(&self) -> usize

Get array length

pub fn is_empty(&self) -> bool

Check if array is empty

pub fn get(&self, index: usize) -> Option<&PdfObject>

Get element at index.

Arguments

• index - Zero-based index

Returns

Reference to the element if index is valid, None otherwise.

Example

use oxidize_pdf::parser::objects::{PdfArray, PdfObject};

let mut array = PdfArray::new();
array.push(PdfObject::Integer(10));
array.push(PdfObject::Integer(20));

assert_eq!(array.get(0).and_then(|o| o.as_integer()), Some(10));
assert_eq!(array.get(1).and_then(|o| o.as_integer()), Some(20));
assert!(array.get(2).is_none());

pub fn push(&mut self, obj: PdfObject)

Push an element

Trait Implementations

impl Clone for PdfArray

fn clone(&self) -> PdfArray

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PdfArray

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

Formats the value using the given formatter.

impl Default for PdfArray

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for PdfArray

fn eq(&self, other: &PdfArray) -> 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.
