Description
Synopsis
- type ForeignPtrs e = GArrayDataR ForeignPtr e
- fromForeignPtrs :: forall sh e. (Shape sh, Elt e) => sh -> ForeignPtrs (EltR e) -> Array sh e
- toForeignPtrs :: forall sh e. (Shape sh, Elt e) => Array sh e -> ForeignPtrs (EltR e)
Documentation
type ForeignPtrs e = GArrayDataR ForeignPtr e Source #
A family of types which represent a collection of ForeignPtr
s. The
structure of the collection depends on the element type e
.
fromForeignPtrs :: forall sh e. (Shape sh, Elt e) => sh -> ForeignPtrs (EltR e) -> Array sh e Source #
O(1). Treat the set of ForeignPtrs
as an Accelerate array. The type of
elements e
in the output Accelerate array determines the structure of the
collection.
Data is considered to be in row-major order. You must ensure that each of the input pointers contains the right number of elements.
The data may not be modified through the ForeignPtr
s afterwards.
You should make sure that the data is suitably aligned.

toForeignPtrs :: forall sh e. (Shape sh, Elt e) => Array sh e -> ForeignPtrs (EltR e) Source #
O(1). Yield the ForeignPtr
s underlying the given Accelerate Array
.
The element type e
will determine the structure of the output collection.
Data is considered to be in row-major order.
