Implementations

impl NETransparentProxyManager

pub unsafe fn loadAllFromPreferencesWithCompletionHandler( completion_handler: &DynBlock<dyn Fn(*mut NSArray<NETransparentProxyManager>, *mut NSError)>, )

Available on crate feature block2 only.

This function asynchronously reads all of the transparent proxy configurations associated with the calling app that have previously been saved to disk and returns them as NETransparentProxyManager objects.

Parameter completionHandler: A block that takes an array NETransparentProxyManager objects. The array passed to the block may be empty if no transparent proxy configurations were successfully read from the disk. The NSError passed to this block will be nil if the load operation succeeded, non-nil otherwise.

impl NETransparentProxyManager

Methods declared on superclass NSObject.

pub unsafe fn init(this: Allocated<Self>) -> Retained<Self>

pub unsafe fn new() -> Retained<Self>

Methods from Deref<Target = NEVPNManager>

pub unsafe fn loadFromPreferencesWithCompletionHandler( &self, completion_handler: &DynBlock<dyn Fn(*mut NSError)>, )

Available on crate feature block2 only.

This function loads the current VPN configuration from the caller’s VPN preferences.

Parameter completionHandler: A block that will be called on the main thread when the load operation is completed. The NSError passed to this block will be nil if the load operation succeeded, non-nil otherwise.

pub unsafe fn removeFromPreferencesWithCompletionHandler( &self, completion_handler: Option<&DynBlock<dyn Fn(*mut NSError)>>, )

Available on crate feature block2 only.

This function removes the VPN configuration from the caller’s VPN preferences. If the VPN is enabled, has VPN On Demand enabled, and has VPN On Demand rules, the VPN is disabled and the VPN On Demand rules are de-activated.

Parameter completionHandler: A block that will be called on the main thread when the remove operation is completed. The NSError passed to this block will be nil if the remove operation succeeded, non-nil otherwise.

pub unsafe fn saveToPreferencesWithCompletionHandler( &self, completion_handler: Option<&DynBlock<dyn Fn(*mut NSError)>>, )

Available on crate feature block2 only.

This function saves the VPN configuration in the caller’s VPN preferences. If the VPN is enabled, has VPN On Demand enabled, and has VPN On Demand rules, the VPN On Demand rules are activated.

Parameter completionHandler: A block that will be called on the main thread when the save operation is completed. The NSError passed to this block will be nil if the save operation succeeded, non-nil otherwise.

pub unsafe fn setAuthorization(&self, authorization: AuthorizationRef)

Available on crate feature objc2-security only.

This function sets an authorization object that can be used to obtain the authorization rights necessary to modify the system VPN configuration.

Parameter authorization: The AuthorizationRef to use to obtain rights.

pub unsafe fn onDemandRules(&self) -> Option<Retained<NSArray<NEOnDemandRule>>>

pub unsafe fn setEnabled(&self, enabled: bool)

Setter for isEnabled.

Methods from Deref<Target = NSObject>

pub fn doesNotRecognizeSelector(&self, sel: Sel) -> !

Handle messages the object doesn’t recognize.

See Apple’s documentation for details.

Methods from Deref<Target = AnyObject>

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());

pub unsafe fn get_ivar<T>(&self, name: &str) -> &T

where T: Encode,

👎Deprecated: this is difficult to use correctly, use 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.

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`
    }
}
