Description
This module contains instances and types necessary for storing wallets in a SQL database with Persistent.
It's in a separate module due to the GHC stage restriction.
The ToJSON/FromJSON and Read instance orphans exist due to class constraints on Persistent functions.

sqlSettings' :: MkPersistSettings Source #
Settings for generating the Persistent types.
aesonFromText :: FromText a => String -> Value -> Parser a Source #
Aeson parser defined in terms of
fromText
fromPersistValueFromText :: FromText a => PersistValue -> Either Text a Source #
fromPersistValue
defined in terms of
fromText
fromPersistValueRead :: Read a => PersistValue -> Either Text a Source #
fromPersistValue
defined in terms of the
Read
class
directionToBool :: Direction -> Bool Source #
directionFromBool :: Bool -> Direction Source #
Wraps 'Hash Tx ' because the persistent entity syntax doesn't seem to support parameterized types.

hashOfNoParent :: Hash "BlockHeader" Source #
Magic value that denotes the hash of the parent of the genesis block (which does not exist). This value is used for serializing the Nothing case of the #parentHeaderHash field.
persistSlotNo :: SlotNo -> PersistValue Source #
persistEpochNo :: EpochNo -> PersistValue Source #
stdGenFromString :: String -> Either Text StdGen Source #
In
random < 1.2
there used to be an
instance Read StdGen
, but no
longer.
The format used to look like this:

stdGenToString :: StdGen -> String Source #
newtype HDPassphrase Source #
Constructors
| HDPassphrase ( Passphrase "addr-derivation-payload") |
Instances
newtype EitherText a Source #
Newtype to get a MonadFail instance for
Either Text
.
We need it to use
parseTimeM
.
