#[repr(C)]pub struct Object(_);Expand description
A type that represents an instance of a class.
Note: This is intentionally neither Sync, Send, UnwindSafe,
RefUnwindSafe nor Unpin, since it is something that changes
depending on the specific subclass.
Examples: NSAutoreleasePool is not Send, it has to be deallocated
on the same thread that it was created. NSLock is not Send either.
Implementations
sourceimpl Object
impl Object
sourcepub unsafe fn ivar<T: Encode>(&self, name: &str) -> &T
pub unsafe fn ivar<T: Encode>(&self, name: &str) -> &T
Returns a shared reference to the ivar with the given name.
Panics
Panics if the object has no ivar with the given name, or the type
encoding of the ivar differs from the type encoding of T.
Safety
The caller must ensure that the ivar is actually of type T.
Library implementors should expose a safe interface to the ivar.
sourcepub unsafe fn get_ivar<T: Encode>(&self, name: &str) -> &T
👎 Deprecated: Use Object::ivar instead.
pub unsafe fn get_ivar<T: Encode>(&self, name: &str) -> &T
Use Object::ivar instead.
sourcepub unsafe fn ivar_mut<T: Encode>(&mut self, name: &str) -> &mut T
pub unsafe fn ivar_mut<T: Encode>(&mut self, name: &str) -> &mut T
Returns a mutable reference to the ivar with the given name.
Panics
Panics if the object has no ivar with the given name, or the type
encoding of the ivar differs from the type encoding of T.
Safety
The caller must ensure that the ivar is actually of type T.
Library implementors should expose a safe interface to the ivar.
sourcepub unsafe fn get_mut_ivar<T: Encode>(&mut self, name: &str) -> &mut T
👎 Deprecated: Use Object::ivar_mut instead.
pub unsafe fn get_mut_ivar<T: Encode>(&mut self, name: &str) -> &mut T
Use Object::ivar_mut instead.
sourcepub unsafe fn set_ivar<T: Encode>(&mut self, name: &str, value: T)
pub unsafe fn set_ivar<T: Encode>(&mut self, name: &str, value: T)
Sets the value of the ivar with the given name.
Panics
Panics if the object has no ivar with the given name, or the type
encoding of the ivar differs from the type encoding of T.
Safety
The caller must ensure that the ivar is actually of type T.
