Struct StackSafeContext 

pub struct StackSafeContext {
    pub depth: usize,
    pub max_depth: usize,
    pub active_stack: Vec<(u32, u16)>,
    pub completed_refs: HashSet<(u32, u16)>,

}

Stack-safe parsing context

Fields

depth: usize

Current recursion depth

max_depth: usize

Maximum allowed depth

active_stack: Vec<(u32, u16)>

Pila de referencias activas (para detectar ciclos reales)

completed_refs: HashSet<(u32, u16)>

Referencias completamente procesadas (no son ciclos)

start_time: Instant

Start time for timeout tracking

timeout: Duration

Timeout duration

Implementations

impl StackSafeContext

pub fn new() -> Self
