mkBuffer :: PrimMonad m => Capacity -> GrowthIncrement -> SpaceAtBottom -> m (DoubleBuffer (PrimState m))

Constructs an new empty FloatBuffer with an initial capacity specified by the codecapacity/code argument.

copyBuffer :: PrimMonad m => DoubleBuffer (PrimState m) -> m (DoubleBuffer (PrimState m))

append :: PrimMonad m => DoubleBuffer (PrimState m) -> Double -> m ()

Appends the given item to the active array and increments the active count. This will expand the array if necessary.
