## 📝 迁移指南
### 从现有 Graph<T, E> 迁移到 VGI
#### 步骤 1: 保持向后兼容
```rust
// 现有代码
use god_graph::graph::Graph;
let mut graph = Graph::<String, f64>::directed();
let a = graph.add_node("A".to_string()).unwrap();
let b = graph.add_node("B".to_string()).unwrap();
graph.add_edge(a, b, 1.0).unwrap();
// 新代码(VGI)
use god_graph::vgi::VirtualGraph;
use god_graph::backend::single_machine::SingleMachineGraph;
let mut graph = SingleMachineGraph::<String, f64>::directed();
let a = graph.add_node("A".to_string()).unwrap();
let b = graph.add_node("B".to_string()).unwrap();
graph.add_edge(a, b, 1.0).unwrap();
```
#### 步骤 2: 实现 VGI trait
```rust
use god_graph::vgi::{VirtualGraph, NodeRef, EdgeRef, GraphMetadata};
use god_graph::vgi::error::GraphResult;
impl<N, E> VirtualGraph for Graph<N, E>
where
N: Clone + Send + Sync,
E: Clone + Send + Sync,
{
type NodeData = N;
type EdgeData = E;
type NodeIndex = usize;
type EdgeIndex = usize;
fn node_count(&self) -> usize {
self.node_count()
}
fn edge_count(&self) -> usize {
self.edge_count()
}
fn get_node(&self, node: Self::NodeIndex) -> GraphResult<&Self::NodeData> {
self.get_node(node).map_err(|e| e.into())
}
// ... 其他方法实现
}
```
