MaybeUninit::fill_slice

[stepancheg]

Add a function:

impl<T> MaybeUninit<T> {
    pub fn fill_slice<'a>(this: &'a mut [MaybeUninit<T>], src: T) -> &'a mut [T]
        where T: Clone,
    { ... }
}

Similarly to slice::fill, it allows fast write of the same element to the slice.

Similarly to MaybeUninit::write_slice_cloned, it returns initialized slice without unsafe code.
