struct CopyOnDrop<'a, T> {
    src: *const T,
    dest: *mut T,
    marker: PhantomData<&'a mut T>,
}
Expand description

When dropped, copies from src into dest.

Fields§

§src: *const T§dest: *mut T§marker: PhantomData<&'a mut T>

src is often a local pointer here, make sure we have appropriate PhantomData so that dropck can protect us.

Implementations§

source§

impl<'a, T> CopyOnDrop<'a, T>

source

unsafe fn new(src: &'a T, dest: *mut T) -> Self

Construct from a source pointer and a destination Assumes dest lives longer than src, since there is no easy way to copy down lifetime information from another pointer
