1. handleGErrorJust :: GErrorClass err => err -> (GErrorMessage -> IO a) -> IO a -> IO a

   haskell-gi-base	Data.GI.Base.GError

   A verson of handleGErrorJust with the arguments swapped around.

2. handleGErrorJustDomain :: GErrorClass err => (err -> GErrorMessage -> IO a) -> IO a -> IO a

   haskell-gi-base	Data.GI.Base.GError

   A verson of catchGErrorJustDomain with the arguments swapped around.

3. whenJust :: Monad m => Maybe a -> (a -> m ()) -> m ()

   haskell-gi-base	Data.GI.Base.Utils

   When the given value is of "Just a" form, execute the given action, otherwise do nothing.

4. _Just :: Prism (Maybe a) (Maybe b) a b

   optics-core	Data.Maybe.Optics

   A Prism that matches on the Just constructor of Maybe.

5. timeZoneAdjustTime :: (HasCallStack, MonadIO m) => TimeZone -> TimeType -> Int64 -> m (Int32, Int64)

   gi-glib	GI.GLib.Structs.TimeZone

   Finds an interval within tz that corresponds to the given time_, possibly adjusting time_ if required to fit into an interval. The meaning of time_ depends on type. This function is similar to timeZoneFindInterval, with the difference that it always succeeds (by making the adjustments described below). In any of the cases where timeZoneFindInterval succeeds then this function returns the same value, without modifying time_. This function may, however, modify time_ in order to deal with non-existent times. If the non-existent local time_ of 02:30 were requested on March 14th 2010 in Toronto then this function would adjust time_ to be 03:00 and return the interval containing the adjusted time. Since: 2.26

6. typeClassAdjustPrivateOffset :: (HasCallStack, MonadIO m) => Ptr () -> Int32 -> m ()

   gi-gobject	GI.GObject.Structs.TypeClass

   No description available in the introspection data.

7. fromJust :: Maybe a -> a

   strict	Data.Strict.Maybe

   Extracts the element out of a Just and throws an error if the argument is Nothing.

8. isJust :: Maybe a -> Bool

   strict	Data.Strict.Maybe

   Yields True iff the argument is of the form Just _.

9. adjustMap :: IsMap map => (MapValue map -> MapValue map) -> ContainerKey map -> map -> map

   mono-traversable	Data.Containers

   Apply a function to the value of a given key. Returns the input map when the key-value pair does not exist.

10. adjustWithKey :: IsMap map => (ContainerKey map -> MapValue map -> MapValue map) -> ContainerKey map -> map -> map

    mono-traversable	Data.Containers

    Equivalent to adjustMap, but the function accepts the key, as well as the previous value.
