Struct dup_indexer::DupIndexer

pub struct DupIndexer<T> { /* private fields */ }

Implementations

impl<T> DupIndexer<T>

pub fn new() -> Self

Create a new instance of DupIndexer<T>, without requiring T to implement Default.

pub fn with_capacity(capacity: usize) -> Self

Constructs a new, empty DupIndexer<T> with at least the specified capacity.

pub fn capacity(&self) -> usize

Returns the total number of elements the indexer can hold without reallocating.

pub fn as_slice(&self) -> &[T]

Extracts a slice containing the entire indexer values.

pub fn len(&self) -> usize

Get the number of values in the indexer.

pub fn is_empty(&self) -> bool

Return true if the indexer is empty.

pub fn into_vec(self) -> Vec<T>

impl<T: Eq + Hash> DupIndexer<T>

pub fn insert(&mut self, value: T) -> usize

Insert a value into the indexer if it doesn’t already exist, and return the index of the value.

Trait Implementations

impl<T: Debug> Debug for DupIndexer<T>

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

Formats the value using the given formatter.

impl<T: Default> Default for DupIndexer<T>

If T implements Default, create a new instance of DupIndexer<T>. Note that DupIndexer::new does not require T to implement Default.

fn default() -> Self

Returns the “default value” for a type.

impl<T> Index<usize> for DupIndexer<T>

type Output = T

The returned type after indexing.

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

Performs the indexing (container[index]) operation.

impl<T> IntoIterator for DupIndexer<T>

type Item = T

The type of the elements being iterated over.

type IntoIter = IntoIter<T, Global>

Which kind of iterator are we turning this into?

fn into_iter(self) -> IntoIter<T>

Creates an iterator from a value.
