setPtr :: (Prim a, PrimMonad m) => Ptr a -> Int -> a -> m ()primitive Data.Primitive.Ptr Fill a memory block with the given value. The length is in elements of type a rather than in bytes.
setByteArray# :: Prim a => MutableByteArray# s -> Int# -> Int# -> a -> State# s -> State# sprimitive Data.Primitive.Types Fill a slice of the mutable array with a value. The offset and length of the chunk are in elements of type a rather than in bytes.
setOffAddr# :: Prim a => Addr# -> Int# -> Int# -> a -> State# s -> State# sprimitive Data.Primitive.Types Fill a memory block given by an address, an offset and a length. The offset and length are in elements of type a rather than in bytes.
setAddrRange# :: Addr# -> Int# -> Int# -> State# RealWorld -> State# RealWorldghc-prim GHC.Prim setAddrRange# dest len c sets all of the bytes in [dest, dest+len) to the value c. Analogous to the standard C function memset, but with a different argument order. Warning: this can fail with an unchecked exception.
setByteArray# :: MutableByteArray# d -> Int# -> Int# -> Int# -> State# d -> State# dghc-prim GHC.Prim setByteArray# ba off len c sets the byte range [off, off+len) of the MutableByteArray# to the byte c. Warning: this can fail with an unchecked exception.
setThreadAllocationCounter# :: Int64# -> State# RealWorld -> State# RealWorldghc-prim GHC.Prim Sets the allocation counter for the current thread to the given value.

set' :: ASetter' s a -> a -> s -> slens Control.Lens.Combinators Replace the target of a Lens or all of the targets of a Setter' or Traversal with a constant value, without changing its type. This is a type restricted version of set, which retains the type of the original.
>>> set' mapped x [a,b,c,d] [x,x,x,x]
>>> set' _2 "hello" (1,"world") (1,"hello")
>>> set' mapped 0 [1,2,3,4] [0,0,0,0]
Note: Attempting to adjust set' a Fold or Getter will fail at compile time with an relatively nice error message.set' :: Setter' s a -> a -> s -> s set' :: Iso' s a -> a -> s -> s set' :: Lens' s a -> a -> s -> s set' :: Traversal' s a -> a -> s -> s
