Struct GraphRef 

pub struct GraphRef<T: Send + Sync> { /* private fields */ }

A cloneable reference that preserves structure during deep cloning.

• Regular clone() creates a shallow copy (same underlying data)
• When cloned during deep_clone(), creates structure-preserving deep copy

Implementations

impl<T: Send + Sync> GraphRef<T>

pub fn get(&self) -> T

where T: Clone,

Get a copy of the referenced value.

pub fn set(&self, value: T)

Set the referenced value.

pub fn update<F>(&self, f: F)

where F: FnOnce(&mut T),

Apply a function to the referenced value.

pub fn index(&self) -> usize

Get the index of this reference within its graph.

pub fn ptr_eq(&self, other: &GraphRef<T>) -> bool

Check if two refs point to the same data (same graph and index).

pub fn same_graph(&self, other: &GraphRef<T>) -> bool

Check if two refs are in the same graph (may have different indices).
