Struct NSException

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

👎Deprecated: icrate::Foundation has been moved to objc2-foundation

Available on crate features Foundation and Foundation_NSException only.

Implementations

impl NSException

pub fn new( name: &NSExceptionName, reason: Option<&NSString>, user_info: Option<&NSDictionary<AnyObject, AnyObject>>, ) -> Option<Id<Self>>

👎Deprecated: icrate::Foundation has been moved to objc2-foundation

Available on crate features Foundation_NSString and Foundation_NSDictionary only.

Create a new NSException object.

Returns None if the exception couldn’t be created (example: If the process is out of memory).

pub unsafe fn raise(&self) -> !

👎Deprecated: icrate::Foundation has been moved to objc2-foundation

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

This is equivalent to using objc2::exception::throw.

Safety

Same as objc2::exception::throw.

pub fn into_exception(this: Id<Self>) -> Id<Exception>

👎Deprecated: icrate::Foundation has been moved to objc2-foundation

Convert this into an Exception object.

pub fn from_exception(obj: Id<Exception>) -> Result<Id<Self>, Id<Exception>>

👎Deprecated: icrate::Foundation has been moved to objc2-foundation

Create this from an Exception object.

This should be considered a hint; it may return Err in very, very few cases where the object is actually an instance of NSException.

Methods from Deref<Target = NSObject>

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

Available on crate feature AuthenticationServices only.

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.

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 unsafe fn get_mut_ivar<T>(&mut self, name: &str) -> &mut T

where T: Encode,

👎Deprecated: this is difficult to use correctly, use Ivar::load_mut instead.

Use Ivar::load_mut 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.
