Struct UniqueContainer 

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

• Each value is unique in this container. if multiple indices have to refer to the same value, then only one index points to the real value and the others point to indirect values, which are just jump indices to the real value.
• You can get a value via its index.

Implementations

impl<T> UniqueContainer<T>

pub fn new() -> Self

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn get(&self, index: usize) -> Option<&T>

pub fn iter(&self) -> PairIter<'_, T>

pub fn values(&self) -> ValueIter<'_, T>

pub fn clear(&mut self)

All indices will be invalidated.

impl<T> UniqueContainer<T>

where T: Hash + Eq,

pub fn truncate(&mut self, len: usize)

Shortens the container to the given length.

All indices beyond the length will be invalidated.

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

Inserts the given value in the container.

If the same value was found by PartialEq, then the old value is replaced with the given new value.

pub fn next_index<Q>(&mut self, value: &Q) -> usize

where Q: Hash + PartialEq<T> + ?Sized,

pub fn replace<Q>(&mut self, old: &Q, new: T) -> bool

where Q: Hash + PartialEq<T> + ?Sized,

pub fn find<Q>(&self, value: &Q) -> Option<usize>

where Q: Hash + PartialEq<T> + ?Sized,

Trait Implementations

impl<T> Default for UniqueContainer<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T> Index<usize> for UniqueContainer<T>

type Output = T

The returned type after indexing.

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

Performs the indexing (container[index]) operation.
