Struct InitializingSlice

Source
struct InitializingSlice<'a, T> {
    data: &'a mut [MaybeUninit<T>],
    initialized_len: usize,
}
Expand description

Ownership of a collection of values stored in a non-owned [MaybeUninit<T>], some of which are not yet initialized. This is sort of like a Vec that doesn’t own its allocation. Its responsibility is to provide cleanup on unwind by dropping the values that are initialized, unless disarmed by forgetting.

This is a helper for impl<T: Clone> CloneToUninit for [T].

Fields§

§data: &'a mut [MaybeUninit<T>]§initialized_len: usize

Number of elements of *self.data that are initialized.
