Explain this code

simple_transactions

这段代码使用了ethers库来与以太坊网络进行交互。代码的主要功能是通过Ganache节点发送一笔交易，并查询交易前后的账户余额。

代码的具体步骤如下：

1. 导入所需的库。
2. 定义一个异步函数 main ，返回一个 Result 类型。
3. 定义一个助记词 mnemonic ，用于生成钱包。
4. 创建一个Ganache节点，并设置助记词为上一步定义的助记词。
5. 打印Ganache节点的HTTP端点地址。
6. 从Ganache节点获取钱包的密钥，并转换为本地钱包类型。
7. 获取钱包的第一个地址，并打印该地址。
8. 创建一个Provider，连接到Ganache节点的端点，并设置轮询间隔为10毫秒。
9. 使用Provider查询第一个地址的余额，并打印余额。
10. 定义一个随机的账户地址，并将其转换为Address类型。
11. 使用Provider查询随机账户的余额，并打印余额。
12. 创建一个交易请求，向随机账户发送1000个以太币，并设置发送者为第一个地址。
13. 使用Provider发送交易，并等待交易确认。
14. 打印交易所在的区块号。
15. 查询随机账户的余额，并打印余额。
16. 返回Ok，表示程序执行成功。

总结：这段代码使用ethers库连接到Ganache节点，发送一笔交易，并查询交易前后的账户余额。

contract_deploy

这段代码是一个使用ethers库与以太坊进行交互的Rust程序。以下是代码的步骤：

1. 导入所需的库。
2. 定义了一个类型别名SignerDeployedContract<T>，表示一个已部署的合约。
3. 定义了一个async的main函数。
4. 设置助记词。
5. 创建一个Ganache实例，并使用助记词生成钱包。
6. 打印Ganache的HTTP端点和钱包的第一个地址。
7. 创建一个Provider实例，并获取Ganache的链ID。
8. 编译Solidity项目。
9. 打印项目的信息。
10. 获取钱包地址的余额。
11. 定义要部署的合约名称。
12. 从项目中找到合约。
13. 获取合约的ABI和字节码。
14. 创建一个签名客户端。
15. 部署合约。
16. 打印部署后的合约地址。

compile函数的作用是编译Solidity项目。它接受一个项目根目录的路径作为参数，并返回一个包含编译输出的结果。

print_project函数用于打印项目的信息。它接受一个ProjectCompileOutput<ConfigurableArtifacts>类型的参数，并打印出每个合约的名称、构造函数和函数。

总之，这段代码的目的是编译Solidity项目并部署一个合约。
