Documentation
arrayFormat :: Char -> Parser ArrayFormat
Parse one of three primitive field formats: array, quoted and plain.
array :: Char -> Parser [ArrayFormat]
Recognizes a quoted string.
plain :: Char -> Parser ByteString
Recognizes a plain string literal, not containing quotes or brackets and not containing the delimiter character.
fmt :: Char -> ArrayFormat -> ByteString
Format an array format item, using the delimiter character if the item is itself an array.
delimit :: Char -> [ArrayFormat] -> ByteString
Format a list of array format items, inserting the appropriate delimiter between them. When the items are arrays, they will be delimited with commas; otherwise, they are delimited with the passed-in-delimiter.
fmt' :: Bool -> Char -> ArrayFormat -> ByteString
Format an array format item, using the delimiter character if the item is
itself an array, optionally applying quoting rules. Creates copies for
safety when used in FromField instances.
esc :: ByteString -> ByteString
Escape a string according to Postgres double-quoted string format.
