Trait Config

pub trait Config:
    Config
    + Config
    + Config<RuntimeEvent: From<Event>> {
    type StateRoot: Get<H256>;
    type PostLogContent: Get<PostLogContent>;
    type ExtraDataLength: 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 StateRoot: Get<H256>

How Ethereum state root is calculated.

type PostLogContent: Get<PostLogContent>

What’s included in the PostLog.

type ExtraDataLength: Get<u32>

The maximum length of the extra data in the Executed event.

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.
