10/// [EIP-7702 Set Code Transaction](https://eips.ethereum.org/EIPS/eip-7702)
11///
12/// This is a helper type to use derive on it instead of manually managing `bitfield`.
13///
14/// By deriving `Compact` here, any future changes or enhancements to the `Compact` derive
15/// will automatically apply to this type.
16///
17/// Notice: Make sure this struct is 1:1 with [`alloy_consensus::TxEip7702`]
