Implementations§
Source§impl MLCTransposeLayer
impl MLCTransposeLayer
Sourcepub unsafe fn dimensions(&self) -> Retained<NSArray<NSNumber>>
👎Deprecated
pub unsafe fn dimensions(&self) -> Retained<NSArray<NSNumber>>
Permutes the dimensions according to ‘dimensions’.
The returned tensor’s dimension i will correspond to dimensions[i].
Sourcepub unsafe fn layerWithDimensions(
dimensions: &NSArray<NSNumber>,
) -> Option<Retained<Self>>
👎Deprecated
pub unsafe fn layerWithDimensions( dimensions: &NSArray<NSNumber>, ) -> Option<Retained<Self>>
Create a transpose layer
Parameter dimensions
: NSArray
<NSNumber
*> representing the desired ordering of dimensions
The dimensions array specifies the input axis source for each output axis, such that the
K’th element in the dimensions array specifies the input axis source for the K’th axis in the
output. The batch dimension which is typically axis 0 cannot be transposed.
Returns: A new transpose layer.
Methods from Deref<Target = MLCLayer>§
Sourcepub unsafe fn layerID(&self) -> NSUInteger
👎Deprecated
pub unsafe fn layerID(&self) -> NSUInteger
The layer ID
A unique number to identify each layer. Assigned when the layer is created.
Sourcepub unsafe fn label(&self) -> Retained<NSString>
👎Deprecated
pub unsafe fn label(&self) -> Retained<NSString>
A string to help identify this object.
Sourcepub unsafe fn isDebuggingEnabled(&self) -> bool
👎Deprecated
pub unsafe fn isDebuggingEnabled(&self) -> bool
A flag to identify if we want to debug this layer when executing a graph that includes this layer
If this is set, we will make sure that the result tensor and gradient tensors are available for reading on CPU The default is NO. If isDebuggingEnabled is set to YES, make sure to set options to enable debugging when compiling the graph. Otherwise this property may be ignored.
Sourcepub unsafe fn setIsDebuggingEnabled(&self, is_debugging_enabled: bool)
👎Deprecated
pub unsafe fn setIsDebuggingEnabled(&self, is_debugging_enabled: bool)
Setter for isDebuggingEnabled
.
Sourcepub unsafe fn deviceType(&self) -> MLCDeviceType
Available on crate feature MLCTypes
only.
pub unsafe fn deviceType(&self) -> MLCDeviceType
MLCTypes
only.The device type where this layer will be executed
Typically the MLCDevice passed to compileWithOptions will be the device used to execute layers in the graph. If MLCDeviceTypeANE is selected, it is possible that some of the layers of the graph may not be executed on the ANE but instead on the CPU or GPU. This property can be used to determine which device type the layer will be executed on.
Methods from Deref<Target = NSObject>§
Sourcepub fn doesNotRecognizeSelector(&self, sel: Sel) -> !
pub fn doesNotRecognizeSelector(&self, sel: Sel) -> !
Handle messages the object doesn’t recognize.
See Apple’s documentation for details.
Methods from Deref<Target = AnyObject>§
Sourcepub fn class(&self) -> &'static AnyClass
pub fn class(&self) -> &'static AnyClass
Dynamically find the class of this object.
§Panics
May panic if the object is invalid (which may be the case for objects
returned from unavailable init
/new
methods).
§Example
Check that an instance of NSObject
has the precise class NSObject
.
use objc2::ClassType;
use objc2::runtime::NSObject;
let obj = NSObject::new();
assert_eq!(obj.class(), NSObject::class());
Sourcepub unsafe fn get_ivar<T>(&self, name: &str) -> &Twhere
T: Encode,
👎Deprecated: this is difficult to use correctly, use Ivar::load
instead.
pub unsafe fn get_ivar<T>(&self, name: &str) -> &Twhere
T: Encode,
Ivar::load
instead.Use Ivar::load
instead.
§Safety
The object must have an instance variable with the given name, and it
must be of type T
.
See Ivar::load_ptr
for details surrounding this.
Sourcepub fn downcast_ref<T>(&self) -> Option<&T>where
T: DowncastTarget,
pub fn downcast_ref<T>(&self) -> Option<&T>where
T: DowncastTarget,
Attempt to downcast the object to a class of type T
.
This is the reference-variant. Use Retained::downcast
if you want
to convert a retained object to another type.
§Mutable classes
Some classes have immutable and mutable variants, such as NSString
and NSMutableString
.
When some Objective-C API signature says it gives you an immutable class, it generally expects you to not mutate that, even though it may technically be mutable “under the hood”.
So using this method to convert a NSString
to a NSMutableString
,
while not unsound, is generally frowned upon unless you created the
string yourself, or the API explicitly documents the string to be
mutable.
See Apple’s documentation on mutability and on
isKindOfClass:
for more details.
§Generic classes
Objective-C generics are called “lightweight generics”, and that’s because they aren’t exposed in the runtime. This makes it impossible to safely downcast to generic collections, so this is disallowed by this method.
You can, however, safely downcast to generic collections where all the
type-parameters are AnyObject
.
§Panics
This works internally by calling isKindOfClass:
. That means that the
object must have the instance method of that name, and an exception
will be thrown (if CoreFoundation is linked) or the process will abort
if that is not the case. In the vast majority of cases, you don’t need
to worry about this, since both root objects NSObject
and
NSProxy
implement this method.
§Examples
Cast an NSString
back and forth from NSObject
.
use objc2::rc::Retained;
use objc2_foundation::{NSObject, NSString};
let obj: Retained<NSObject> = NSString::new().into_super();
let string = obj.downcast_ref::<NSString>().unwrap();
// Or with `downcast`, if we do not need the object afterwards
let string = obj.downcast::<NSString>().unwrap();
Try (and fail) to cast an NSObject
to an NSString
.
use objc2_foundation::{NSObject, NSString};
let obj = NSObject::new();
assert!(obj.downcast_ref::<NSString>().is_none());
Try to cast to an array of strings.
use objc2_foundation::{NSArray, NSObject, NSString};
let arr = NSArray::from_retained_slice(&[NSObject::new()]);
// This is invalid and doesn't type check.
let arr = arr.downcast_ref::<NSArray<NSString>>();
This fails to compile, since it would require enumerating over the array to ensure that each element is of the desired type, which is a performance pitfall.
Downcast when processing each element instead.
use objc2_foundation::{NSArray, NSObject, NSString};
let arr = NSArray::from_retained_slice(&[NSObject::new()]);
for elem in arr {
if let Some(data) = elem.downcast_ref::<NSString>() {
// handle `data`
}
}
