Trait UnsafePtr

pub trait UnsafePtr {
    // Required method
    fn as_any(&self) -> &(dyn Any + 'static);

    // Provided methods
    fn eq(&self, _: &dyn UnsafePtr) -> bool { ... }

}

Required Methods

fn as_any(&self) -> &(dyn Any + 'static)

For downcasting

Provided Methods

fn eq(&self, _: &dyn UnsafePtr) -> bool

fn ref_sub_one(&self)

for gc

fn mark_dirty(&self, _: &mut VecDeque<i32>)

for gc

fn can_make_cycle(&self) -> bool

Returns true if the user data can make reference cycles, so that GC can

fn break_cycle(&self)

If can_make_cycle returns true, implement this to break cycle
