  1. ErrorFormat :: Error

    persistent-sqlite Database.Sqlite

    No documentation available.

  2. ansiForeground :: AnsiStyle -> Maybe (Intensity, Color)

    prettyprinter-ansi-terminal Prettyprinter.Render.Terminal.Internal

    Set the foreground color, or keep the old one.

  3. setLogFormat :: (Utf8Builder -> Utf8Builder) -> LogOptions -> LogOptions

    rio RIO

    Set format method for messages Default: id

  4. setLogVerboseFormat :: Bool -> LogOptions -> LogOptions

    rio RIO

    Use the verbose format for printing log messages. Default: follows the value of the verbose flag.

  5. setLogVerboseFormatIO :: IO Bool -> LogOptions -> LogOptions

    rio RIO

    Refer to setLogVerboseFormat. This modifier allows to alter the verbose format value dynamically at runtime. Default: follows the value of the verbose flag.

  6. bifor :: (Bitraversable t, Applicative f) => t a b -> (a -> f c) -> (b -> f d) -> f (t c d)

    rio RIO.Prelude

    bifor is bitraverse with the structure as the first argument. For a version that ignores the results, see bifor_.

    Examples

    Basic usage:
    >>> bifor (Left []) listToMaybe (find even)
    Nothing
    
    >>> bifor (Left [1, 2, 3]) listToMaybe (find even)
    Just (Left 1)
    
    >>> bifor (Right [4, 5]) listToMaybe (find even)
    Just (Right 4)
    
    >>> bifor ([1, 2, 3], [4, 5]) listToMaybe (find even)
    Just (1,4)
    
    >>> bifor ([], [4, 5]) listToMaybe (find even)
    Nothing
    

  7. bifor_ :: (Bifoldable t, Applicative f) => t a b -> (a -> f c) -> (b -> f d) -> f ()

    rio RIO.Prelude

    As bitraverse_, but with the structure as the primary argument. For a version that doesn't ignore the results, see bifor.

    Examples

    Basic usage:
    >>> bifor_ ("Hello", True) print (print . show)
    "Hello"
    "True"
    
    >>> bifor_ (Right True) print (print . show)
    "True"
    
    >>> bifor_ (Left "Hello") print (print . show)
    "Hello"
    

  8. pattern BeforeCommonEra :: Integer -> Year

    rio RIO.Time

    Also known as Before Christ. Note that Year 1 = 1 CE, and the previous Year 0 = 1 BCE. CommonEra and BeforeCommonEra form a COMPLETE set.

  9. iso8601DateFormat :: Maybe String -> String

    rio RIO.Time

    Construct format string according to ISO-8601. The Maybe String argument allows to supply an optional time specification. E.g.:

    iso8601DateFormat Nothing            == "%Y-%m-%d"           -- i.e. YYYY-MM-DD
    iso8601DateFormat (Just "%H:%M:%S")  == "%Y-%m-%dT%H:%M:%S"  -- i.e. YYYY-MM-DDTHH:MM:SS
    

  10. rfc822DateFormat :: String

    rio RIO.Time

    Format string according to RFC822.
