Struct BGProcessingTask

#[repr(C)]
pub struct BGProcessingTask {
    pub ptr: Id<Object>,
}

A time-consuming processing task that runs while the app is in the background.

Fields

ptr: Id<Object>

The raw pointer to the Objective-C object.

Methods from Deref<Target = Object>

pub fn class(&self) -> &Class

Returns the class of self.

pub unsafe fn get_ivar<T>(&self, name: &str) -> &T

where T: Encode,

Returns a reference to the ivar of self with the given name. Panics if self has no ivar with the given name. Unsafe because the caller must ensure that the ivar is actually of type T.

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

where T: Encode,

Returns a mutable reference to the ivar of self with the given name. Panics if self has no ivar with the given name. Unsafe because the caller must ensure that the ivar is actually of type T.

pub unsafe fn set_ivar<T>(&mut self, name: &str, value: T)

where T: Encode,

Sets the value of the ivar of self with the given name. Panics if self has no ivar with the given name. Unsafe because the caller must ensure that the ivar is actually of type T.
