# Rect::Contains (Vector2)

```cpp
bool Contains(const Vector2& point) const
```

检测 Vector2 点是否在矩形内。

**参数：**
- `point` - 要检测的二维点

**返回：** `bool` - 点在矩形内（包含边界）返回 true

**复杂度：** O(1)

**示例：**

```cpp
Rect rect(0.0f, 0.0f, 100.0f, 100.0f);
Vector2 point(50.0f, 50.0f);
if (rect.Contains(point)) {
    // 点在矩形内
}
```
