Convenience macro to instantiate an EIP-712 domain.

This macro allows you to instantiate an EIP-712 domain struct without manually writing None for unused fields.

It may be used to declare a domain with any combination of fields. Each field must be labeled with the name of the field, and the fields must be in order. The fields for the domain are:

• name
• version
• chain_id
• verifying_contract
• salt

Examples

const MY_DOMAIN: Eip712Domain = eip712_domain! {
    name: "MyCoolProtocol",
};

let dynamic_name = String::from("MyCoolProtocol");
let my_other_domain: Eip712Domain = eip712_domain! {
    name: dynamic_name,
    version: "1.0.0",
    salt: keccak256("my domain salt"),
};
