Provided Methods

fn gpuResourceID(&self) -> MTLResourceID

where Self: Sized + Message,

Available on crate feature MTLTypes only.

A handle that represents the GPU resource, which you can store in an argument buffer.

fn buffer(&self) -> Option<Retained<ProtocolObject<dyn MTLBuffer>>>

where Self: Sized + Message,

Available on crate feature MTLBuffer only.

A buffer instance this tensor shares its storage with or nil if this tensor does not wrap an underlying buffer.

fn bufferOffset(&self) -> NSUInteger

where Self: Sized + Message,

An offset, in bytes, into the buffer instance this tensor shares its storage with, or zero if this tensor does not wrap an underlying buffer.

fn strides(&self) -> Option<Retained<MTLTensorExtents>>

where Self: Sized + Message,

An array of strides, in elements, one for each dimension of this tensor.

This property only applies if this tensor shares its storage with a buffer, otherwise it’s nil.

fn dimensions(&self) -> Retained<MTLTensorExtents>

where Self: Sized + Message,

An array of sizes, in elements, one for each dimension of this tensor.

fn dataType(&self) -> MTLTensorDataType

where Self: Sized + Message,

An underlying data format of this tensor.

fn usage(&self) -> MTLTensorUsage

where Self: Sized + Message,

A set of contexts in which you can use this tensor.

unsafe fn replaceSliceOrigin_sliceDimensions_withBytes_strides( &self, slice_origin: &MTLTensorExtents, slice_dimensions: &MTLTensorExtents, bytes: NonNull<c_void>, strides: &MTLTensorExtents, )

where Self: Sized + Message,

Replaces the contents of a slice of this tensor with data you provide.

• Parameters:
• sliceOrigin: An array of offsets, in elements, to the first element of the slice that this method writes data to.
• sliceDimensions: An array of sizes, in elements, of the slice this method writes data to.
• bytes: A pointer to bytes of data that this method copies into the slice you specify with sliceOrigin and sliceDimensions.
• strides: An array of strides, in elements, that describes the layout of the data in bytes. You are responsible for ensuring strides meets the following requirements:
• Elements of stridesare in monotonically non-decreasing order.
• For any i larger than zero, strides[i] is greater than or equal to strides[i-1] * dimensions[i-1].

Safety

bytes must be a valid pointer.

unsafe fn getBytes_strides_fromSliceOrigin_sliceDimensions( &self, bytes: NonNull<c_void>, strides: &MTLTensorExtents, slice_origin: &MTLTensorExtents, slice_dimensions: &MTLTensorExtents, )

where Self: Sized + Message,

Copies the data corresponding to a slice of this tensor into a pointer you provide.

• Parameters:
• bytes: A pointer to bytes of data that this method copies into the slice you specify with sliceOrigin and sliceDimensions.
• strides: An array of strides, in elements, that describes the layout of the data in bytes. You are responsible for ensuring strides meets the following requirements:
• Elements of stridesare in monotonically non-decreasing order.
• For any i larger than zero, strides[i] is greater than or equal to strides[i-1] * dimensions[i-1].
• sliceOrigin: An array of offsets, in elements, to the first element of the slice that this method reads data from.
• sliceDimensions: An array of sizes, in elements, of the slice this method reads data from.

Safety

bytes must be a valid pointer.
