Implementations§

Source §

impl ASAuthorizationProviderExtensionKerberosMapping

Source

pub unsafe fn ticketKeyPath(&self) -> Option<Retained<NSString>>

The keypath in the response JSON that uses this set of mappings.

If the response tokens from login contain this keypath, then the mapping in this class will be used to create a Kerberos ticket. The expected response is a JSON dictionary with the supplied key names.

Source

pub unsafe fn setTicketKeyPath(&self, ticket_key_path: Option<&NSString>)

Setter for ticketKeyPath.

Source

pub unsafe fn messageBufferKeyName(&self) -> Option<Retained<NSString>>

The key name that contains the base64 encoded kerberos AS-REP string.

Source

pub unsafe fn setMessageBufferKeyName( &self, message_buffer_key_name: Option<&NSString>, )

Setter for messageBufferKeyName.

Source

pub unsafe fn realmKeyName(&self) -> Option<Retained<NSString>>

The key name that contains the Kerberos Realm string.

Source

pub unsafe fn setRealmKeyName(&self, realm_key_name: Option<&NSString>)

Setter for realmKeyName.

Source

pub unsafe fn serviceNameKeyName(&self) -> Option<Retained<NSString>>

The key name that contains the Kerberos service name string.

Source

pub unsafe fn setServiceNameKeyName( &self, service_name_key_name: Option<&NSString>, )

Setter for serviceNameKeyName.

Source

pub unsafe fn clientNameKeyName(&self) -> Option<Retained<NSString>>

The key name that contains the Kerberos client name string.

Source

pub unsafe fn setClientNameKeyName( &self, client_name_key_name: Option<&NSString>, )

Setter for clientNameKeyName.

Source

pub unsafe fn encryptionKeyTypeKeyName(&self) -> Option<Retained<NSString>>

The key name that contains the Kerberos session key type number.

The value for this key should be the correct encryption type per RFC3962, section 7 for the session key.

Source

pub unsafe fn setEncryptionKeyTypeKeyName( &self, encryption_key_type_key_name: Option<&NSString>, )

Setter for encryptionKeyTypeKeyName.

Source

pub unsafe fn sessionKeyKeyName(&self) -> Option<Retained<NSString>>

The key name that contains the Kerberos session key.

Source

pub unsafe fn setSessionKeyKeyName( &self, session_key_key_name: Option<&NSString>, )

Setter for sessionKeyKeyName.

impl ASAuthorizationProviderExtensionKerberosMapping

Methods declared on superclass NSObject.

Source

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

Source

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

Methods from Deref<Target = NSObject>§

Source

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

Handle messages the object doesn’t recognize.

See Apple’s documentation for details.

Methods from Deref<Target = AnyObject>§

Source

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());

Source

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.

Source

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`
    }
}
