TX_Storage -> DataKey, SC_Transfers -> TransferInternal, TransferExternal

this package exports an interface which is used by blockchain to persist/query data

DataKey

type DataKey struct {
    SCID    crypto.Key // tx which created the the contract or contract ID
    Key     Variable
    Special bool // whether the value is generic or special , special is used to store DERO value
}

DataAtom

type DataAtom struct {
    Key DataKey

    Prev_Value Variable // previous Value if any
    Value      Variable // current value if any
}

TransferInternal

type TransferInternal struct {
    Received []uint64
    Sent     []uint64
}

TransferExternal

// any external tranfers
type TransferExternal struct {
    Address string `msgpack:"A,omitempty" json:"A,omitempty"` //  transfer to this blob
    Amount  uint64 `msgpack:"V,omitempty" json:"V,omitempty"` // Amount in Atomic units
}

SC_Transfers

type SC_Transfers struct {
    BalanceAtStart uint64             // value at start
    TransferI      TransferInternal   // all internal transfers
    TransferE      []TransferExternal // all external transfers
}

TX_Storage

// all SC load and store operations will go though this
type TX_Storage struct {
    DiskLoader func(DataKey, *uint64) Variable
    Atoms      []DataAtom           // all modification operations have to played/reverse in this order
    Keys       map[DataKey]Variable // this keeps the in-transit DB updates, just in case we have to discard instantly

    Transfers map[crypto.Key]SC_Transfers // all transfers ( internal/external )
}
