7/// [EIP-1559 Transaction](https://eips.ethereum.org/EIPS/eip-1559)
8///
9/// This is a helper type to use derive on it instead of manually managing `bitfield`.
10///
11/// By deriving `Compact` here, any future changes or enhancements to the `Compact` derive
12/// will automatically apply to this type.
13///
14/// Notice: Make sure this struct is 1:1 with [`alloy_consensus::TxEip1559`]
