pub unsafe fn user_data(&self) -> Option<Box<dyn FnMut()>>

Get the user data

Safety

Can return multiple mutable instances of the user data, which has a different lifetime than the object

pub unsafe fn set_user_data(&mut self, data: *mut c_void)

Manually set the user data

Safety

Manually set the user data, the data validity can't be checked since it's opaque

pub fn set_callback(&mut self, cb: Box<dyn FnMut()>)
