Struct InitializingSlice
pub(in ::clone::uninit) struct InitializingSlice<'a, T> { pub(in ::clone::uninit) data: &'a mut [MaybeUninit<T>], pub(in ::clone::uninit) initialized_len: usize }
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: usizeNumber of elements of
*self.datathat are initialized.
Implementations
impl<'a, T> InitializingSlice<'a, T>
fn from_fully_uninit(data: &'a mut [MaybeUninit<T>]) -> Selffn push(&mut self, value: T)Push a value onto the end of the initialized part of the slice.
Panics
Panics if the slice is already fully initialized.
