Implementations

impl IndexSet

pub fn empty() -> Self

Create an empty set.

pub fn len(&self) -> usize

Get the number of indices.

pub fn is_empty(&self) -> bool

Check if the set is empty.

pub fn contains(&self, index: usize) -> bool

Check if the given index is contained.

pub fn indices(&self) -> impl Iterator<Item = usize> + '_

Iterator over indices.

pub fn to_vec(&self) -> Vec<usize>

Convert to Vec<usize>.

pub fn to_bitset(&self) -> FixedBitSet

Convert to FixedBitSet.

pub fn indices_as_u32(&self) -> impl Iterator<Item = u32> + '_

pub fn to_vec_as_u32(&self) -> Vec<u32>

Convert to Vec<u32>. Please only use this when converting to protobuf.

pub fn insert(&mut self, index: usize)

Insert an index.

impl Clone for IndexSet

fn clone(&self) -> IndexSet

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IndexSet

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

Formats the value using the given formatter.

impl Extend<usize> for IndexSet

fn extend<T: IntoIterator<Item = usize>>(&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<Vec<usize>> for IndexSet

fn from(vec: Vec<usize>) -> Self

Converts to this type from the input type.

impl FromIterator<usize> for IndexSet

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

Creates a value from an iterator.

impl Hash for IndexSet

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for IndexSet

fn eq(&self, other: &IndexSet) -> 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.
