#[repr(C)]pub struct NSCollectionViewUpdateItem { /* private fields */ }
Available on crate feature
NSCollectionViewLayout
only.Implementations§
source§impl NSCollectionViewUpdateItem
impl NSCollectionViewUpdateItem
pub unsafe fn indexPathBeforeUpdate(&self) -> Option<Retained<NSIndexPath>>
pub unsafe fn indexPathAfterUpdate(&self) -> Option<Retained<NSIndexPath>>
pub unsafe fn updateAction(&self) -> NSCollectionUpdateAction
Methods from Deref<Target = NSObject>§
sourcepub fn doesNotRecognizeSelector(&self, sel: Sel) -> !
pub fn doesNotRecognizeSelector(&self, sel: Sel) -> !
Handle messages the object doesn’t recognize.
See Apple’s documentation for details.
Methods from Deref<Target = AnyObject>§
sourcepub fn class(&self) -> &'static AnyClass
Available on crate feature NSAccessibilityConstants
only.
pub fn class(&self) -> &'static AnyClass
NSAccessibilityConstants
only.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());
sourcepub unsafe fn get_ivar<T>(&self, name: &str) -> &Twhere
T: Encode,
👎Deprecated: this is difficult to use correctly, use Ivar::load
instead.Available on crate feature NSAccessibilityConstants
only.
pub unsafe fn get_ivar<T>(&self, name: &str) -> &Twhere
T: Encode,
Ivar::load
instead.NSAccessibilityConstants
only.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.
sourcepub unsafe fn get_mut_ivar<T>(&mut self, name: &str) -> &mut Twhere
T: Encode,
👎Deprecated: this is difficult to use correctly, use Ivar::load_mut
instead.Available on crate feature NSAccessibilityConstants
only.
pub unsafe fn get_mut_ivar<T>(&mut self, name: &str) -> &mut Twhere
T: Encode,
Ivar::load_mut
instead.NSAccessibilityConstants
only.Use Ivar::load_mut
instead.
§Safety
The object must have an instance variable with the given name, and it
must be of type T
.
