Struct fruity::foundation::NSException

#[repr(C)]
pub struct NSException(_);

A special condition that interrupts the normal flow of program execution.

See documentation.

Implementations

impl NSException

Creating and rasing exceptions.

pub fn raise(&self) -> !

Raises the receiver, causing program flow to jump to the local exception handler.

When there are no exception handlers in the exception handler stack, unless the exception is raised during the posting of a notification, this method calls the uncaught exception handler, in which last-minute logging can be performed. The program then terminates, regardless of the actions taken by the uncaught exception handler.

See documentation.

impl NSException

Querying an NSException object.

pub fn name(&self) -> Arc<NSExceptionName>

Returns a string used to uniquely identify self.

See documentation.

pub fn reason(&self) -> Option<Arc<NSString<'_>>>

Returns a containing a “human-readable” reason for self.

See documentation.

Methods from Deref<Target = NSObject<'static>>

pub fn retain_count(&self) -> usize

Returns this object’s reference count.

This method is only useful for debugging certain objects.

See documentation.

pub fn responds_to_selector(&self, selector: Sel) -> bool

Returns true if this object implements or inherits a method that can respond to a specified message.

See documentation.

pub fn is_kind_of_class(&self, class: &Class) -> bool

Returns true if this object is an instance or subclass of class.

See documentation

pub fn is_member_of_class(&self, class: &Class) -> bool

Returns true if this object is an instance of class.

See documentation

pub fn hash(&self) -> NSUInteger

Returns an integer that can be used as a table address in a hash table structure.

See documentation.

pub fn copy(&self) -> Arc<Self>

Returns a copy of this object using NSCopying.

See documentation.

pub fn mutable_copy(&self) -> Arc<Self>

Returns a copy of this object using NSMutableCopying.

See documentation.

pub fn description(&self) -> Arc<NSString<'static>>

Returns a string that describes the contents of this object.

See documentation

pub fn debug_description(&self) -> Arc<NSString<'static>>

Returns a string that describes the contents of the receiver for presentation in the debugger.

See documentation

Trait Implementations

impl AsMut<NSException> for NSException

fn as_mut(&mut self) -> &mut Self

Converts this type into a mutable reference of the (usually inferred) input type.

impl<T> AsMut<T> for NSException where
    NSObject<'static>: AsMut<T>, 

fn as_mut(&mut self) -> &mut T

Converts this type into a mutable reference of the (usually inferred) input type.

impl AsRef<NSException> for NSException

fn as_ref(&self) -> &Self

Converts this type into a shared reference of the (usually inferred) input type.

impl<T> AsRef<T> for NSException where
    NSObject<'static>: AsRef<T>, 

fn as_ref(&self) -> &T

Converts this type into a shared reference of the (usually inferred) input type.

impl ClassType<'static> for NSException

fn class() -> &'static Class

Returns the Objective-C class that can be used to instantiate a new instance of Self.

impl Deref for NSException

type Target = NSObject<'static>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl ObjectType for NSException

fn retain(obj: &Self) -> Arc<Self>

Increments the object’s retain count and returns a smart pointer that automatically calls release on Drop.

unsafe fn release(obj: NonNull<Self>)

Decrements the object’s retain count.

impl ObjectType<'static> for NSException

fn as_objc_object(&self) -> &ObjCObject<'data>

Casts self into a type-erased Objective-C object.

fn class<'s>(&'s self) -> &'s Class where
    'data: 's, 

Returns the class that this object is an instance of.
