Struct objc2::foundation::NSThread
source · #[repr(C)]pub struct NSThread { /* private fields */ }Expand description
A thread of execution.
Implementations§
Methods from Deref<Target = NSObject>§
sourcepub fn is_kind_of<T: ClassType>(&self) -> bool
pub fn is_kind_of<T: ClassType>(&self) -> bool
Check if the object is an instance of the class, or one of it’s subclasses.
See Apple’s documentation for more details on what you may (and what you may not) do with this information.
Methods from Deref<Target = Object>§
sourcepub unsafe fn ivar_ptr<T: Encode>(&self, name: &str) -> *mut T
pub unsafe fn ivar_ptr<T: Encode>(&self, name: &str) -> *mut T
Returns a pointer to the instance variable / ivar with the given name.
This is similar to UnsafeCell::get, see that for more information
on what is and isn’t safe to do.
Usually you will have defined the instance variable yourself with
ClassBuilder::add_ivar, the type of the ivar T must match the
type used in that.
Attempting to access or modify private implementation details of a class that you do no control using this is not supported, and may invoke undefined behaviour.
Library implementors are strongly encouraged to expose a safe interface to the ivar.
Panics
May panic if the object has no ivar with the given name. May also
panic if the type encoding of the ivar differs from the type encoding
of T.
This should purely seen as help while debugging and is not guaranteed
(e.g. it may be disabled when debug_assertions are off).
Safety
The object must have an instance variable with the given name, and it
must be of type T. Any invariants that the object have assumed about
the value of the instance variable must not be violated.
No thread syncronization is done on accesses to the variable, so you must ensure that any access to the returned pointer do not cause data races, and that Rust’s mutability rules are not otherwise violated.
sourcepub unsafe fn ivar<T: Encode>(&self, name: &str) -> &T
pub unsafe fn ivar<T: Encode>(&self, name: &str) -> &T
Returns a reference to the instance variable with the given name.
See Object::ivar_ptr for more information, including on when this
panics.
Safety
The object must have an instance variable with the given name, and it
must be of type T.
No thread syncronization is done, so you must ensure that no other
thread is concurrently mutating the variable. This requirement can be
considered upheld if all mutation happens through Object::ivar_mut
(since that takes &mut self).
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
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.
See Object::ivar_ptr for more information, including on when this
panics.
Safety
The object must have an instance variable with the given name, and it
must be of type T.
This access happens through &mut self, which means we know it to be
the only reference, hence you do not need to do any work to ensure
that data races do not happen.
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
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.
This is just a helpful shorthand for Object::ivar_mut, see that
for more information.
Safety
Same as Object::ivar_mut.
