Trait Config

pub trait Config: Config {
    type MaxChanges: Get<u32>;
    type MaxKeyLength: Get<u32>;
    type MaxValueLength: Get<u32>;

Configuration trait of this pallet.

The main purpose of this trait is to act as an interface between this pallet and the runtime in which it is embedded in. A type, function, or constant in this trait is essentially left to be configured by the runtime that includes this pallet.

Consequently, a runtime that wants to include this pallet must implement this trait.

Required Associated Types

type MaxChanges: Get<u32>

Maximum number of changes that can be registered in a single inherent.

This value must be high enough for all changes to be registered in one block. Setting this to a value higher than the total number of parameters in the Governed Map guarantees that.

type MaxKeyLength: Get<u32>

Maximum length of the key in the Governed Map in bytes.

This value must be high enough not to be exceeded by any key stored on Cardano.

type MaxValueLength: Get<u32>

Maximum length of data stored under a single key in the Governed Map

This value must be high enough not to be exceeded by any value stored on Cardano.

type OnGovernedMappingChange: OnGovernedMappingChange<Self::MaxKeyLength, Self::MaxValueLength>

Handler called for each change in the governed mappings.

If your runtime does not need to react to any changes, a no-op implementation for [()] can be used. Otherwise, it is advised to benchmark the runtime and use your own weights to include weight consumed by the handler.

type MainChainScriptsOrigin: EnsureOrigin<Self::RuntimeOrigin>

Origin for governance calls

type WeightInfo: WeightInfo

Weight functions for the pallet’s extrinsics

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
