Control.Quiver.CSV

Description

Aan efficient Quiver-based implementation of a cellular CSV encoder and decoder, designed for fast streaming of data with guaranteed constant memory usage.

Synopsis

Documentation

data CSVError Source

Codec error type.

Constructors

IncompleteCell	Input ends in a partial cell value. For encoder, this means that the last `Cell` of the input stream specifies the `EOP` delimiter instead of `EOR` or `EOT`. For decoder, this means that the last cell of the input stream is missing the closing quote character.
IncompleteRow	Input ends in a partial row value. For encoder, this means that the last `Cell` of the input stream specifies the `EOC` delimiter instead of `EOR` or `EOT`. For decoder, this means that the last row of the input stream is missing the line break sequence.

Instances

Enum CSVError Source
Eq CSVError Source
Ord CSVError Source
Show CSVError Source

decodeCSV :: Functor f => SP ByteString (Cell ByteString) f CSVError Source

A Quiver processor that parses a fragmented strict representation of a CSV file into a stream of cells.

decodeLazyCSV :: Functor f => SP ByteString (Cell ByteString) f CSVError Source

A Quiver processor that parses a fragmented lazy representation of a CSV file into a stream of cells.

encodeCSV :: Int -> SP (Cell ByteString) ByteString f CSVError Source

encodeCSV n is an infinite pipe that converts a stream of cells into a fragmented strict representation of a CSV file, unconditionally quoting any field values with length greater than n.

encodeLazyCSV :: Int -> SP (Cell ByteString) ByteString f CSVError Source

encodeLazyCSV n is an infinite pipe that converts a stream of cells into a fragmented lazy representation of a CSV file, unconditionally quoting any field values with length greater than n.
