Struct MovableBackref 

Source 
pub struct MovableBackref<T: 'static> { /* private fields */ }
Expand description

A backref record submitted alongside each item in a TypedMovableSection. This points to a MovableRef that lives outside of the section.

Implementations§

Source§

impl<T> MovableBackref<T>

Source

pub fn current_ptr(&self) -> *const T

Current value of the stable pointer slot as a pointer.

Source

pub unsafe fn set_current_ptr(&self, ptr: *const T)

Update the stable pointer slot.

§Safety

Updating the slot requires exclusive access. See Exclusive access for more information. Any live &T or MovableRef dereference may alias the old or new target.
