// # Dev-note: The value of the `ContractsRawCode` has a unique implementation of serialization
// and deserialization and uses `Raw` codec. Because the value is a contract byte code represented
// by bytes, we don't use `serde::Deserialization` and `serde::Serialization` for `Vec`,
// because we don't need to store the size of the contract. We store/load raw bytes.
