[docs] Add in notice about requirement for serialization/deserialization for middleware #8094
Description
Within the using ibc-go --> middleware --> Create a custom IBC middleware section, add in a notice that middleware developers must use the same serialization and deserialization method as in ibc-go's codec: transfertypes.ModuleCdc.[Must]MarshalJSON
For middleware builders this means:
import transfertypes "github.com/cosmos/ibc-go/v10/modules/apps/transfer/types"
transfertypes.ModuleCdc.[Must]MarshalJSON
func MarshalAsIBCDoes(ack channeltypes.Acknowledgement) ([]byte, error) {
return transfertypes.ModuleCdc.MarshalJSON(&ack)
}
