授权托盘

一个 Substrate 托盘，允许从运行时模块（如 collective）使用 sudo 函数。

用法

添加依赖

编辑 runtime/Cargo.toml 并添加以下内容

[dependencies.mandate]
default-features = false
version = '2.0.0'
package = "pallet-mandate"

然后将 mandate/std 添加到 [features] 部分，它应该看起来像这样

[dependencies.mandate]
default-features = false
version = '2.0.0'
package = "pallet-mandate"

[features]
default = ['std']
std = [
    # Your substrate modules /std calls here
    # ...

    'mandate/std',
]

将模块添加到您的运行时

特质实现

您可以使用 ExternalOrigin 类型来指定谁可以向模块调度调用。例如，您可以与 collective 一起使用。

impl mandate::Trait for Runtime {
    type Proposal = Call;

    // A majority of the committee can dispatch root calls
    type ExternalOrigin =
        collective::EnsureProportionAtLeast<_1, _2, AccountId, TechnicalCollective>;
}

添加模块

在 construct_runtime 宏调用中，只需添加 Mandate: mandate::{Module, Call}，它应该看起来像这样

construct_runtime!(
    pub enum Runtime where
        Block = Block,
        NodeBlock = Block,
        UncheckedExtrinsic = UncheckedExtrinsic
    {
    	// Your modules here
    	// ...
        Mandate: mandate::{Module, Call},
    }
);
