1. setField :: forall (f :: Symbol) s a . HasField' f s a => a -> s -> s

   generic-lens	Data.Generics.Product.Fields

   >>> setField @"age" 60 human
   Human {name = "Tunyasz", age = 60, address = "London", other = False}
   

2. setPosition :: forall (i :: Nat) s a . HasPosition' i s a => a -> s -> s

   generic-lens	Data.Generics.Product.Positions

   >>> setPosition @2 60 human
   Human {name = "Tunyasz", age = 60, address = "London"}
   

3. setTyped :: HasType a s => a -> s -> s

   generic-lens	Data.Generics.Product.Typed

   Set field at type.

4. setComp :: Strategy r => Comp -> Array r ix e -> Array r ix e

   massiv	Data.Massiv.Array

   Set computation strategy for this array

   Example

   >>> :set -XTypeApplications
   
   >>> import Data.Massiv.Array
   
   >>> a = singleton @DL @Ix1 @Int 0
   
   >>> a
   Array DL Seq (Sz1 1)
   [ 0 ]
   
   >>> setComp (ParN 6) a -- use 6 capabilities
   Array DL (ParN 6) (Sz1 1)
   [ 0 ]
   

5. setComp :: Strategy r => Comp -> Array r ix e -> Array r ix e

   massiv	Data.Massiv.Core

   Set computation strategy for this array

   Example

   >>> :set -XTypeApplications
   
   >>> import Data.Massiv.Array
   
   >>> a = singleton @DL @Ix1 @Int 0
   
   >>> a
   Array DL Seq (Sz1 1)
   [ 0 ]
   
   >>> setComp (ParN 6) a -- use 6 capabilities
   Array DL (ParN 6) (Sz1 1)
   [ 0 ]
   

6. setDim' :: (HasCallStack, Index ix) => ix -> Dim -> Int -> ix

   massiv	Data.Massiv.Core.Index

   Change the value of a specific dimension within the index. See setDimM for a safer version and setDimension for a type safe version.

   Examples

   >>> setDim' (2 :> 3 :> 4 :. 5) 3 10
   2 :> 10 :> 4 :. 5
   

7. setDimM :: (Index ix, MonadThrow m) => ix -> Dim -> Int -> m ix

   massiv	Data.Massiv.Core.Index

   Set the value for an index at specified dimension.

8. setDimension :: forall ix (n :: Natural) . IsIndexDimension ix n => ix -> Dimension n -> Int -> ix

   massiv	Data.Massiv.Core.Index

   Type safe way to set value of index at a particular dimension.

   Examples

   >>> setDimension (2 :> 3 :> 4 :. 5) Dim4 10
   10 :> 3 :> 4 :. 5
   

9. setSzM :: (MonadThrow m, Index ix) => Sz ix -> Dim -> Sz Int -> m (Sz ix)

   massiv	Data.Massiv.Core.Index

   Same as setDimM, but for Sz

   Example

   >>> import Data.Massiv.Core.Index
   
   >>> setSzM (Sz2 2 3) 2 (Sz1 1) :: IO Sz2
   Sz (1 :. 3)
   
   >>> setSzM (Sz2 2 3) 3 (Sz1 1) :: IO Sz2
   *** Exception: IndexDimensionException: (Dim 3) for (2 :. 3)
   

10. setUnliftedArray :: (PrimMonad m, PrimUnlifted a) => MutableUnliftedArray (PrimState m) a -> a -> Int -> Int -> m ()

    primitive-unlifted	Data.Primitive.Unlifted.Array
