Struct Content 

pub struct Content<T> {
    pub object: T,
    pub state: GraphicsState,
    pub marks: ContentMarks,
    pub content_stream: Option<usize>,
    pub dirty: bool,
    pub active: bool,
}

A page object with the state and marks it was created under.

Fields

object: T

The object itself.

state: GraphicsState

The graphics state in force at its creation.

marks: ContentMarks

The marked-content sequence enclosing it.

content_stream: Option<usize>

Which /Contents element it came from, for the editor, or None for an object that was created rather than parsed.

None sorts before Some(0) — Option’s own Ord — which is what gives a brand-new object the lowest free /Contents index in the regenerator’s ordered walk rather than one past the end.

dirty: bool

Whether the object has been changed since it was parsed, so its content stream must be written again on save (see PageObject::set_active).

active: bool

Whether the object is painted. An inactive object keeps its place in the list but contributes nothing to a regenerated stream.

Implementations

impl<T> Content<T>

pub fn new(object: T, state: GraphicsState) -> Self

A newly created object, under state and enclosed by no marks.

It arrives dirty and streamless, which is what a created object is: it describes no bytes yet, so the stream it lands in has to be written for it to exist at all. An object the interpreter produced from bytes is built field-by-field instead, because it is neither.
