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.
