Synopsis

Documentation

arrayFormat :: Char -> Parser ArrayFormat Source #

Parse one of three primitive field formats: array, quoted and plain.

quoted :: Parser ByteString Source #

Recognizes a quoted string.

plain :: Char -> Parser ByteString Source #

Recognizes a plain string literal, not containing quotes or brackets and not containing the delimiter character.

fmt :: Char -> ArrayFormat -> ByteString Source #

Format an array format item, using the delimiter character if the item is itself an array.

delimit :: Char -> [ArrayFormat] -> ByteString Source #

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 Source #

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 Source #

Escape a string according to Postgres double-quoted string format.
