Struct PyVisit

pub struct PyVisit<'a> {
    pub(crate) visit: visitproc,
    pub(crate) arg: *mut c_void,
    pub(crate) _guard: PhantomData<&'a ()>,
}

Expand description

Object visitor for GC.

Fields§

§visit: visitproc§arg: *mut c_void§_guard: PhantomData<&'a ()>

Prevents the PyVisit from outliving the __traverse__ call.
