Struct intrusive_collections::IntrusiveRef

pub struct IntrusiveRef<T: ?Sized> {
    // some fields omitted
}

Pointer to an object that may be part of one or more intrusive colllections

This pointer guarantees that an object managed by an IntrusiveRef is not moved, dropped or accessed through a mutable reference as long as at least one IntrusiveRef is pointing to it.

Methods

impl<T: ?Sized> IntrusiveRef<T>

unsafe fn from_raw(val: *const T) -> IntrusiveRef<T>

Creates an IntrusiveRef from a raw pointer

Safety

You must ensure that the IntrusiveRef guarantees are upheld.

fn into_raw(self) -> *mut T

Converts an IntrusiveRef into a raw pointer

impl<T: ?Sized> IntrusiveRef<T>

fn from_box(val: Box<T>) -> IntrusiveRef<T>

Creates an IntrusiveRef from a Box

unsafe fn into_box(self) -> Box<T>

Converts an IntrusiveRef into a Box

Safety

You must ensure that this is the only IntrusiveRef managing this object and that it is not currently a member of any intrusive collections. This operation is only valid if the IntrusiveRef was created using IntrusiveRef::from_box.
