Struct UninitWriteView 

pub struct UninitWriteView<'a, T, PW: OptionalWaiter, CW: OptionalWaiter> {
    pub slices: (&'a mut [MaybeUninit<T>], &'a mut [MaybeUninit<T>]),
    /* private fields */
}

View into the writable portion of the buffer, with uninitialized elements.

Using this is unsafe, as an accurate number of items produces must be given, otherwise this will produce uninitialized values to the consumer.

Fields

slices: (&'a mut [MaybeUninit<T>], &'a mut [MaybeUninit<T>])

Implementations

impl<'a, T, PW: OptionalWaiter, CW: OptionalWaiter> UninitWriteView<'a, T, PW, CW>

pub unsafe fn produce(self, amnt: usize)

Produces the specified number of items, making them available to the receiver.

The remaining elements are assumed to be uninitialzed and will not be accessed.

amnt is clamped to the number of items in this view.

Safety

The elements being produced must have been initialized.

pub fn iter( &mut self, ) -> Chain<IterMut<'_, MaybeUninit<T>>, IterMut<'_, MaybeUninit<T>>>

Iterates through each available slot, in order.

Equivalent to chaining the two slice’s iterators.

pub fn is_empty(&self) -> bool

Checks if the view is empty.

Equivalent to testing if the first slices is empty. If the first slice is empty, the second one will be as well.

pub fn len(&self) -> usize

Gets the length of the view.

This is the sum of the lengths of both slices.

pub fn get(&mut self, i: usize) -> Option<&mut MaybeUninit<T>>

Gets an item from the view, at the i’th place, or None if out of bounds.

Mimics slice::get_mut.

Trait Implementations

impl<'a, T, PW: OptionalWaiter, CW: OptionalWaiter> Deref for UninitWriteView<'a, T, PW, CW>

type Target = (&'a mut [MaybeUninit<T>], &'a mut [MaybeUninit<T>])

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'a, T, PW: OptionalWaiter, CW: OptionalWaiter> DerefMut for UninitWriteView<'a, T, PW, CW>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl<'a, T, PW: OptionalWaiter, CW: OptionalWaiter> Index<usize> for UninitWriteView<'a, T, PW, CW>

type Output = MaybeUninit<T>

The returned type after indexing.

fn index(&self, i: usize) -> &Self::Output

Performs the indexing (container[index]) operation.

impl<'a, T, PW: OptionalWaiter, CW: OptionalWaiter> IndexMut<usize> for UninitWriteView<'a, T, PW, CW>

fn index_mut(&mut self, i: usize) -> &mut MaybeUninit<T>

Performs the mutable indexing (container[index]) operation.
