Struct NEOnDemandRuleDisconnect

Source

#[repr(C)]
pub struct NEOnDemandRuleDisconnect { /* private fields */ }

Expand description

The NEOnDemandRuleDisconnect class declares the programmatic interface for an object that defines an On Demand rule with the “Disconnect” action.

When rules of this class match, the VPN connection is not started, and the VPN connection is disconnected if it is not currently disconnected.

Instances of this class are thread safe.

Implementations§

Source §

impl NEOnDemandRuleDisconnect

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 = NEOnDemandRule>§

Source

pub unsafe fn action(&self) -> NEOnDemandRuleAction

The rule’s action

Source

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

An array of NSString objects. If the current default search domain is equal to one of the strings in this array and all of the other conditions in the rule match, then the rule matches. If this property is nil (the default), then the current default search domain does not factor into the rule match.

Source

pub unsafe fn setDNSSearchDomainMatch( &self, dns_search_domain_match: Option<&NSArray<NSString>>, )

Setter for DNSSearchDomainMatch.

Source

pub unsafe fn DNSServerAddressMatch( &self, ) -> Option<Retained<NSArray<NSString>>>

An array of DNS server IP addresses represented as NSString objects. If each of the current default DNS servers is equal to one of the strings in this array and all of the other conditions in the rule match, then the rule matches. If this property is nil (the default), then the default DNS servers do not factor into the rule match.

Source

pub unsafe fn setDNSServerAddressMatch( &self, dns_server_address_match: Option<&NSArray<NSString>>, )

Setter for DNSServerAddressMatch.

Source

pub unsafe fn interfaceTypeMatch(&self) -> NEOnDemandRuleInterfaceType

The type of interface that this rule matches. If the current primary network interface is of this type and all of the other conditions in the rule match, then the rule matches. If this property is 0 (the default), then the current primary interface type does not factor into the rule match.

Source

pub unsafe fn setInterfaceTypeMatch( &self, interface_type_match: NEOnDemandRuleInterfaceType, )

Setter for interfaceTypeMatch.

Source

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

An array of NSString objects. If the Service Set Identifier (SSID) of the current primary connected network matches one of the strings in this array and all of the other conditions in the rule match, then the rule matches. If this property is nil (the default), then the current primary connected network SSID does not factor into the rule match.

Source

pub unsafe fn setSSIDMatch(&self, ssid_match: Option<&NSArray<NSString>>)

Setter for SSIDMatch.

Source

pub unsafe fn probeURL(&self) -> Option<Retained<NSURL>>

An HTTP or HTTPS URL. If a request sent to this URL results in a HTTP 200 OK response and all of the other conditions in the rule match, then then rule matches. If this property is nil (the default), then an HTTP request does not factor into the rule match.

Source

pub unsafe fn setProbeURL(&self, probe_url: Option<&NSURL>)

Setter for probeURL.

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`
    }
}
