1. mapAccumulator :: (m -> n) -> FunctionBuilder m a b -> FunctionBuilder n a b

   function-builder	Data.FunctionBuilder

   Convert the accumulated (usually monoidal-) value, this allows to change the underlying accumlator type.

2. mapNext :: (s -> r) -> FunctionBuilder m r a -> FunctionBuilder m s a

   function-builder	Data.FunctionBuilder

   Convert the output of a FunctionBuilder value; since most FunctionBuilders are parameteric in r they also have r in a in a, such that a always either is r or is a function returning r eventually. In order to get from a FunctionBuilder that can accept a continuation returning it an r to a FunctionBuilder that accepts continuations returning an s instead, we need to apply a function s -> r to the return value of the continuation. Note that a mapNext will not only change the r to an s but probably also the the a, when it is parametric, as in this contrived example:

   example :: Int -> x -> Sum Int
   example = toFunction (ign add)
   
   add :: FunctionBuilder (Sum Int) next (Int -> next)
   add = FB (\k x -> k $ Sum x)
   
   ign :: FunctionBuilder m (x -> r) a -> FunctionBuilder m r a
   ign = mapNext const
   

   Here the extra parameter x is pushed down into the a of the add FunctionBuilder.

3. mapGetView :: (HasCallStack, MonadIO m, IsMap a) => a -> m (Maybe View)

   gi-gtksource5	GI.GtkSource.Objects.Map

   Gets the [propertymap:view] property, which is the view this widget is mapping.

4. mapNew :: (HasCallStack, MonadIO m) => m Map

   gi-gtksource5	GI.GtkSource.Objects.Map

   Creates a new GtkSourceMap.

5. mapSetView :: (HasCallStack, MonadIO m, IsMap a, IsView b) => a -> b -> m ()

   gi-gtksource5	GI.GtkSource.Objects.Map

   Sets the view that map will be doing the mapping to.

6. mapAllocationSuccessful :: (HasCallStack, MonadIO m) => MapT -> m Int32

   gi-harfbuzz	GI.HarfBuzz.Functions

   Tests whether memory allocation for a set was successful. Since: 1.7.7

7. mapClear :: (HasCallStack, MonadIO m) => MapT -> m ()

   gi-harfbuzz	GI.HarfBuzz.Functions

8. mapCopy :: (HasCallStack, MonadIO m) => MapT -> m MapT

   gi-harfbuzz	GI.HarfBuzz.Functions

   Allocate a copy of map. Since: 4.4.0

9. mapCreate :: (HasCallStack, MonadIO m) => m MapT

   gi-harfbuzz	GI.HarfBuzz.Functions

   Creates a new, initially empty map. Since: 1.7.7

10. mapDel :: (HasCallStack, MonadIO m) => MapT -> Word32 -> m ()

    gi-harfbuzz	GI.HarfBuzz.Functions

    Removes key and its stored value from map. Since: 1.7.7
