1//! PageObject enum for custom filtering.
2//!
3//! [`PageObject`] wraps references to different page object types (characters,
4//! lines, rectangles, curves, images) so that a single predicate function can
5//! inspect any object on a page.

9/// An enum wrapping references to different page object types.
10///
11/// Used as the argument to filter predicates, allowing users to match on
12/// specific object types and inspect their properties.
13///
14/// # Example
15///
16/// ```ignore
17/// // Keep only characters with font "Helvetica" and all non-char objects
18/// page.filter(|obj| match obj {
19///     PageObject::Char(c) => c.fontname == "Helvetica",
20///     _ => true,
21/// });
22/// ```
23pub enum PageObject<'a> {
24    /// A character object.
25    Char(&'a Char),
26    /// A line object.
27    Line(&'a Line),
28    /// A rectangle object.
29    Rect(&'a Rect),
30    /// A curve object.
31    Curve(&'a Curve),
32    /// An image object.
33    Image(&'a Image),
