目标
1、如何配置instantiable pallets
用例
- 一个代币链承载两种独立的加密货币。
- 治理有两个（或更多）内部运作类似的机构。
- 维护不同金库的社交网络链。
概述
Instantiable pallets为包含多个对同一pallet引用的运行时提供单独的存储项目。这对重用单个托盘提供的逻辑的情况下很有用。接下来展示如何创建同一个托盘的两个实例以及如何配置它们的功能。
步骤
1.实现Instance类型
instantiable pallets必须调用decl_storage!宏才能Instance创建类型。
Instance在 Config trait、Event 类型和 Store trait 中添加一个泛型类型。 下面的代码片段显示了pallet的Config和Store trait所需的修改：
pub trait Config<I: Instance>: frame_system::Config {
type Event: From<Event<Self>> + Into<<Self as frame_system::Config>::Event>;
}
/// Include the I: Instance type parameter in storage declaration
decl_storage! {
trait Store for Module<T: Config<I>, I: Instance> as MintToken {
/* --snip-- */
- 配置你的运行时
包括mint_tokenin 的两个实例runtime/src/lib.rs：
/* --snip-- */
// Instance1 of mint_token
impl mint_token::Config<mint_token::Instance1> for Runtime {
type Event = Event;
}
// Instance2 of mint_token
impl mint_token::Config<mint_token::Instance2> for Runtime {
type Event = Event;
}
/* --snip-- */
MintToken1: mint_token::<Instance1>::{Pallet, Call, Storage, Event<T>},
MintToken2: mint_token::<Instance2>::{Pallet, Call, Storage, Event<T>},
/* --snip-- */
