Function rel_core::rel_mem::replace_unsized_unchecked

pub unsafe fn replace_unsized_unchecked<T, R, E>(dest: In<Mut<'_, T>, R>, src: E)where
    T: DropRaw + Pointee + ?Sized,
    R: Region,
    E: Emplace<T, R>,

Replaces the unsized value in dest by emplacing src into it.

Safety

The caller must guarantee that dest must have the metadata returned from src.emplaced_meta.
