Trait Implementations

impl<'a, VC: AsBytes<'a>> AsBytes<'a> for Bools<VC, &'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<VC: Clear> Clear for Bools<VC>

fn clear(&mut self)

Clears self, without changing its capacity.

impl<VC: Clone, WC: Clone> Clone for Bools<VC, WC>

fn clone(&self) -> Bools<VC, WC>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<VC: Container<u64>> Container<bool> for Bools<VC>

type Borrowed<'a> = Bools<<VC as Container<u64>>::Borrowed<'a>, &'a u64> where VC: 'a

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<VC: Debug, WC: Debug> Debug for Bools<VC, WC>

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

Formats the value using the given formatter.

impl<VC: Default, WC: Default> Default for Bools<VC, WC>

fn default() -> Bools<VC, WC>

Returns the “default value” for a type.

impl<'de, VC, WC> Deserialize<'de> for Bools<VC, WC>

where VC: Deserialize<'de>, WC: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a, VC: FromBytes<'a>> FromBytes<'a> for Bools<VC, &'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<VC: HeapSize> HeapSize for Bools<VC>

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

Active (len) and allocated (cap) heap sizes in bytes. This should not include the size of self itself.

impl<VC: Len + IndexAs<u64>, WC: Copy + CopyAs<u64>> Index for Bools<VC, WC>

type Ref = bool

The type returned by the get method.

fn get(&self, index: usize) -> Self::Ref

fn last(&self) -> Option<Self::Ref>

where Self: Len,

fn iter(&self) -> IterOwn<&Self>

fn into_iter(self) -> IterOwn<Self>

where Self: Sized,

impl<VC: Len, WC: Copy + CopyAs<u64>> Len for Bools<VC, WC>

fn len(&self) -> usize

The number of contained elements.

fn is_empty(&self) -> bool

Whether this contains no elements.

impl<VC: PartialEq, WC: PartialEq> PartialEq for Bools<VC, WC>

fn eq(&self, other: &Bools<VC, WC>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<'a, VC: Push<u64>> Push<&'a bool> for Bools<VC>

fn push(&mut self, bit: &'a bool)

Pushes an item onto self.

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

Pushes elements of an iterator onto self.

impl<VC: Push<u64>> Push<bool> for Bools<VC>

fn push(&mut self, bit: bool)

Pushes an item onto self.

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

Pushes elements of an iterator onto self.

impl<VC, WC> Serialize for Bools<VC, WC>

where VC: Serialize, WC: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
