关于Object Wrapping的疑问

[fyang1024]

https://docs.sui.io/build/programming-with-objects/ch4-object-wrapping 提到

There are some interesting consequences of wrapping a Sui object into another. When an object is wrapped, the object no longer exists independently on-chain. You can no longer look up the object by its ID. The object becomes part of the data of the object that wraps it. Most importantly, you can no longer pass the wrapped object as an argument in any way in Sui Move calls. The only access point is through the wrapping object.

为什么 https://github.com/MystenLabs/sui/blob/d0f9a3047879f600bc61c94e519ad91bd6a8f0cd/sui_programmability/examples/objects_tutorial/sources/trusted_swap.move#L72-L73 能把object1和object2作为参数传递给transfer::transfer函数?

这么久无人回答，我只好自问自答了

因为 https://github.com/MystenLabs/sui/blob/d0f9a3047879f600bc61c94e519ad91bd6a8f0cd/sui_programmability/examples/objects_tutorial/sources/trusted_swap.move#L57-L69 这段代码就是 unwrap 过程，object1 和 object2 经过 unwrap 就可以被作为参数传递，或被 transfer::transfer 函数转移了
