readColumn Source #

Arguments

:: ServerInfo	Server information is needed in case of some parameters are missing
-> Int	number of rows
-> ByteString	data type
-> Reader (Vector ClickhouseType)

writeColumn Source #

Arguments

:: Context	context contains client information and server information
-> ByteString	column name
-> ByteString	column type (String, Int, etc)
-> Vector ClickhouseType	items to be serialized.
-> Writer Builder	result wrapped in a customized Writer Monad used for concatenating string builders.
