10 solana账户转换问题？

老师们好，我在写solana时遇到一个问题，问题代码如下，我如何将receivers(pubkey类型), to: receiver.to_account_info()是错误的，如何才能在to中使用AccountInfo类型？报错如下：
he method `to_account_info` exists for struct `Pubkey`, but its trait bounds were not satisfied
   --> src/lib.rs:148:30
    |
148 |                 to: receiver.to_account_info(),
    |                              ^^^^^^^^^^^^^^^ method cannot be called on `Pubkey` due to unsatisfied trait bounds
删掉to_account_info()则报错不是AccountInfo类型。
