Implementations

impl DeletionVector

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

Trait Implementations

impl Clone for DeletionVector

fn clone(&self) -> DeletionVector

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DeletionVector

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

Formats the value using the given formatter.

impl Default for DeletionVector

fn default() -> Self

Returns the “default value” for a type.

impl Extend<u32> for DeletionVector

fn extend<T: IntoIterator<Item = u32>>(&mut self, iter: T)

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

🔬This is a nightly-only experimental API. (extend_one)

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one)

Reserves capacity in a collection for the given number of additional elements.

impl From<&DeletionVector> for RoaringBitmap

fn from(value: &DeletionVector) -> Self

Converts to this type from the input type.

impl FromIterator<u32> for DeletionVector

fn from_iter<T: IntoIterator<Item = u32>>(iter: T) -> Self

Creates a value from an iterator.

impl IntoIterator for DeletionVector

impl DeletionVector { pub fn get(i: u32) -> bool { … } } impl BitAnd for DeletionVector { … }

type IntoIter = Box<dyn Iterator<Item = <DeletionVector as IntoIterator>::Item>>

Which kind of iterator are we turning this into?

type Item = u32

The type of the elements being iterated over.

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for DeletionVector

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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