Database.CQL.Protocol.Internal

Like Database.CQL.Protocol but exports the whole encode/decode machinery for all types.

Cql type-class

class Cql a where

A type that can be converted from and to some CQL Value.

This type-class is used to map custom types to Cassandra data-types. For example:

newtype MyType = MyType Int32

instance Cql MyType where
    ctype              = Tagged IntColumn
    toCql (MyType i)   = CqlInt i
    fromCql (CqlInt i) = Right (MyType i)
    fromCql _          = Left "Expected CqlInt"

data Row

A row is a vector of Values.

Instances

Eq Row

Methods

(==) :: Row -> Row -> Bool

(/=) :: Row -> Row -> Bool

Show Row

Methods

showsPrec :: Int -> Row -> ShowS

show :: Row -> String

showList :: [Row] -> ShowS

Tuple Row

mkRow :: [(Value, ColumnType)] -> Row

fromRow :: Cql a => Int -> Row -> Either String a

Convert a row element.

columnTypes :: Row -> [ColumnType]

rowLength :: Row -> Int

class Record a where

Record/Tuple conversion. For example:

data Peer = Peer
    { peerAddr :: IP
    , peerRPC  :: IP
    , peerDC   :: Text
    , peerRack :: Text
    } deriving Show

recordInstance ''Peer

map asRecord <$> performQuery "SELECT peer, rpc_address, data_center, rack FROM system.peers"

The generated type-class instance maps between record and tuple constructors:

type instance TupleType Peer = (IP, IP, Text, Text)

instance Record Peer where
    asTuple (Peer a b c d) = (a, b, c, d)
    asRecord (a, b, c, d)  = Peer a b c d

Minimal complete definition

asTuple, asRecord

Methods

asTuple :: a -> TupleType a

asRecord :: TupleType a -> a

type family TupleType a
