Struct ObjectWalker 

pub struct ObjectWalker { /* private fields */ }

Iterative BFS walker for the PDF object graph.

Traverses objects starting from a root, tracking visited objects to detect cycles. Enforces a safety limit of MAX_OBJECT_NUMBER visited objects to prevent denial of service.

Implementations

impl ObjectWalker

pub fn new() -> Self

Create a new walker with the default safety limit.

pub fn with_max_objects(max_objects: usize) -> Self

Create a new walker with a custom maximum objects limit.

pub fn walk<S: PdfSource>( &mut self, store: &ObjectStore<S>, root_id: ObjectId, visitor: &mut dyn ObjectVisitor, )

Walk the object graph starting from root_id, calling visitor methods for each object encountered.

Uses iterative BFS with cycle detection. Silently skips objects that cannot be resolved from the store.

pub fn visited_count(&self) -> usize

Returns the number of unique objects visited so far.

pub fn visited(&self) -> &HashSet<ObjectId>

Returns a reference to the set of visited object IDs.

Trait Implementations

impl Default for ObjectWalker

fn default() -> Self

Returns the “default value” for a type.
