9/// Transaction with an [`AccessList`] ([EIP-2930](https://eips.ethereum.org/EIPS/eip-2930)).
10///
11/// This is a helper type to use derive on it instead of manually managing `bitfield`.
12///
13/// By deriving `Compact` here, any future changes or enhancements to the `Compact` derive
14/// will automatically apply to this type.
15///
16/// Notice: Make sure this struct is 1:1 with [`alloy_consensus::TxEip2930`]
