Solana Anchor如何定义带有结构数组的自定义类型？

Question

在将我的结构移动到pub mod xyz {.}之后，我的锈蚀代码：

#[state]
#[derive(Default)]
#[derive(Copy)]//index as pid
pub struct Ppool {
  pub alloc_point: u64,
}
#[state]
pub struct Counter {
    pub authority: Pubkey,
    pub count: u64,
    pub pool_array: [Ppool; 20],
}

impl Counter {
    pub fn new(ctx: Context<Auth>) -> Result<Self> {
        Ok(Self {
            authority: *ctx.accounts.authority.key,
            count: 0,
            pool_array: [
              Ppool {
              alloc_point: 0,
            }; 20],
        })
    }

我的Rust程序可以编译，但是Anchor没有错误地运行：

await program.state.rpc.new({
  accounts: {
    authority: provider.wallet.publicKey,
  },
});

TypeError:无法读取未定义的属性rpc

我从本教程Basic1：https://project-serum.github.io/anchor/tutorials/tutorial-1.html#defining-a-program中了解到，“如果您希望将自己的类型作为指令处理程序的输入传递，那么必须在与#程序模块相同的src/lib.rs文件中定义它，这样IDL解析器就可以获取它。”

此外，如果我将Ppool结构移出mod之外，Rust将编译，但是Anchor会说"Error:用户定义的类型未提供“.所以我认为Ppool结构应该留在国防部内部

但是在将我的Ppool结构移动到mod之后，我的Ppool结构就不能有#状态.见以下错误：

在mod中，我应该为我的Ppool结构添加什么样的宏？

通过将数组放入结构数组来解决.请参阅Anchor repo >test>零副本
