type BoltActionT = ReaderT Pipe #
Monad Transformer to do all BOLT actions in
run :: Pipe -> BoltActionT m a -> m a #
Runs BOLT action on selected pipe
queryP :: MonadIO m => Text -> Map Text Value -> BoltActionT m [Record] #
Runs Cypher query with parameters and returns list of obtained Records. Strict version
query :: MonadIO m => Text -> BoltActionT m [Record] #
Runs Cypher query and returns list of obtained Records. Strict version
queryP_ :: MonadIO m => Text -> Map Text Value -> BoltActionT m () #
Runs Cypher query with parameters and ignores response
query_ :: MonadIO m => Text -> BoltActionT m () #
Runs Cypher query and ignores response

The BoltValue class describes values, that can be packed and unpacked for BOLT protocol.
Methods
pack :: a -> ByteString #
Packs a value to ByteString
unpackT :: Monad m => UnpackT m a #
Unpacks in a State monad to get values from single ByteString
unpack :: Monad m => ByteString -> m a #
Unpacks a ByteString to selected value
