Trait Implementations

impl<'a> AsBytes<'a> for Empties<&'a u64>

fn as_bytes(&self) -> impl Iterator<Item = (u64, &'a [u8])>

Presents self as a sequence of byte slices, with their required alignment.

fn length_in_words(&self) -> usize

The number of u64 words required to record self as aligned bytes.

impl Clear for Empties

fn clear(&mut self)

Clears self, without changing its capacity.

impl<CC: Clone> Clone for Empties<CC>

fn clone(&self) -> Empties<CC>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Container<()> for Empties

type Borrowed<'a> = Empties<&'a u64>

The type of a borrowed container.

fn borrow<'a>(&'a self) -> Self::Borrowed<'a>

Converts a reference to the type to a borrowed variant.

impl<CC: Debug> Debug for Empties<CC>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<CC: Default> Default for Empties<CC>

fn default() -> Empties<CC>

Returns the “default value” for a type.

impl<'a> FromBytes<'a> for Empties<&'a u64>

fn from_bytes(bytes: &mut impl Iterator<Item = &'a [u8]>) -> Self

Reconstructs self from a sequence of correctly aligned and sized bytes slices.

impl HeapSize for Empties

fn heap_size(&self) -> (usize, usize)

impl<CC: CopyAs<u64> + Copy> Len for Empties<CC>

fn len(&self) -> usize

The number of contained elements.

fn is_empty(&self) -> bool

Whether this contains no elements.

impl Push<&()> for Empties

fn push(&mut self, _item: &())

Pushes an item onto self.

fn extend(&mut self, iter: impl IntoIterator<Item = T>)
