Struct refmove::RefMove [−][src]
pub struct RefMove<'a, T: ?Sized + 'a> { /* fields omitted */ }
Owned reference.
RefMove<'a, T>
inherits both &'a mut T
and Box<T>
. For example,
- As in
RefMove<'a, T>
,RefMove<'a, T>
is covariant w.r.t.'a
. - As in
Box<T>
,RefMove<'a, T>
is covariant w.r.t.T
. - As in
Box<T>
,RefMove<'a, T>
has a destructor. However, unlikeBox<T>
, it only destructs its contents and does not free the pointer itself. - Therefore,
RefMove<'a, T>
can refer to the stack like&'a mut T
. - Like
Box<T>
, you can extractT
from it.
Methods
impl<'a, T: 'a> RefMove<'a, T>
[src]
impl<'a, T: 'a> RefMove<'a, T>
pub unsafe fn from_mut(reference: &'a mut ManuallyDrop<T>) -> Self
[src]
pub unsafe fn from_mut(reference: &'a mut ManuallyDrop<T>) -> Self
Creates RefMove
from its ManuallyDrop
reference.
It works much like ManuallyDrop::drop
but the actual drop of the content delays until RefMove
is dropped.
Safety
This function eventually (by expiration of 'a
lifetime) runs
the destructor of the contained value and thus the wrapped value
represents uninitialized data after 'a
.
It is up to the user of this method to ensure the uninitialized data
is actually used.
Sizedness
This function currently imposes the T: Sized
bound.
T: ?Sized
is just blocked by #53033 in the compiler.
impl<'a, T: ?Sized + 'a> RefMove<'a, T>
[src]
impl<'a, T: ?Sized + 'a> RefMove<'a, T>
pub unsafe fn from_ptr(ptr: *mut T) -> Self
[src]
pub unsafe fn from_ptr(ptr: *mut T) -> Self
Creates RefMove
from a pointer.
Safety
ptr
must point to a memory region that is valid until
expiration of 'a
lifetime.
The memory region must not be shared by another.
The memory region must initially contain the valid content.
After expiration of 'a
lifetime, the region is uninitialized.
