Module stack_safe 

Stack-safe parsing utilities

This module provides utilities for parsing deeply nested PDF structures without risking stack overflow. It implements recursion limits and iterative alternatives to recursive algorithms.

Structs

RecursionGuard

RAII guard for recursion depth tracking

ReferenceStackGuard

RAII guard for reference stack tracking

StackSafeContext

Stack-safe parsing context

Constants

MAX_RECURSION_DEPTH

Maximum recursion depth for PDF parsing operations

PARSING_TIMEOUT_SECS

Timeout for long-running parsing operations (in seconds)
