# Struct indexmap::set::IndexSet [−][src]

pub struct IndexSet<T, S = RandomState> { /* fields omitted */ }

## Expand description

A hash set where the iteration order of the values is independent of their hash values.

The interface is closely compatible with the standard `HashSet`

, but also
has additional features.

# Order

The values have a consistent order that is determined by the sequence of insertion and removal calls on the set. The order does not depend on the values or the hash function at all. Note that insertion order and value are not affected if a re-insertion is attempted once an element is already present.

All iterators traverse the set *in order*. Set operation iterators like
`union`

produce a concatenated order, as do their matching “bitwise”
operators. See their documentation for specifics.

The insertion order is preserved, with **notable exceptions** like the
`.remove()`

or `.swap_remove()`

methods. Methods such as `.sort_by()`

of
course result in a new order, depending on the sorting order.

# Indices

The values are indexed in a compact range without holes in the range
`0..self.len()`

. For example, the method `.get_full`

looks up the index for
a value, and the method `.get_index`

looks up the value by index.

# Examples

use indexmap::IndexSet; // Collects which letters appear in a sentence. let letters: IndexSet<_> = "a short treatise on fungi".chars().collect(); assert!(letters.contains(&'s')); assert!(letters.contains(&'t')); assert!(letters.contains(&'u')); assert!(!letters.contains(&'y'));

## Implementations

`impl<T> IndexSet<T>`

[src]

`impl<T> IndexSet<T>`

[src]`pub fn with_capacity(n: usize) -> Self`

[src]

`pub fn with_capacity(n: usize) -> Self`

[src]Create a new set with capacity for `n`

elements.
(Does not allocate if `n`

is zero.)

Computes in **O(n)** time.

`impl<T, S> IndexSet<T, S>`

[src]

`impl<T, S> IndexSet<T, S>`

[src]`pub fn with_capacity_and_hasher(n: usize, hash_builder: S) -> Self`

[src]

`pub fn with_capacity_and_hasher(n: usize, hash_builder: S) -> Self`

[src]Create a new set with capacity for `n`

elements.
(Does not allocate if `n`

is zero.)

Computes in **O(n)** time.

`pub fn with_hasher(hash_builder: S) -> Self`

[src]

`pub fn with_hasher(hash_builder: S) -> Self`

[src]Create a new set with `hash_builder`

`pub fn is_empty(&self) -> bool`

[src]

`pub fn is_empty(&self) -> bool`

[src]Returns true if the set contains no elements.

Computes in **O(1)** time.

`pub fn iter(&self) -> Iter<'_, T>ⓘ`

[src]

`pub fn iter(&self) -> Iter<'_, T>ⓘ`

[src]Return an iterator over the values of the set, in their order

`pub fn clear(&mut self)`

[src]

`pub fn clear(&mut self)`

[src]Remove all elements in the set, while preserving its capacity.

Computes in **O(n)** time.

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

[src]

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

[src]Shortens the set, keeping the first `len`

elements and dropping the rest.

If `len`

is greater than the set’s current length, this has no effect.

`pub fn drain<R>(&mut self, range: R) -> Drain<'_, T>ⓘ where`

R: RangeBounds<usize>,

[src]

`pub fn drain<R>(&mut self, range: R) -> Drain<'_, T>ⓘ where`

R: RangeBounds<usize>,

[src]Clears the `IndexSet`

in the given index range, returning those values
as a drain iterator.

The range may be any type that implements `RangeBounds<usize>`

,
including all of the `std::ops::Range*`

types, or even a tuple pair of
`Bound`

start and end values. To drain the set entirely, use `RangeFull`

like `set.drain(..)`

.

This shifts down all entries following the drained range to fill the gap, and keeps the allocated memory for reuse.

* Panics* if the starting point is greater than the end point or if
the end point is greater than the length of the set.

`pub fn split_off(&mut self, at: usize) -> Self where`

S: Clone,

[src]

`pub fn split_off(&mut self, at: usize) -> Self where`

S: Clone,

[src]Splits the collection into two at the given index.

Returns a newly allocated set containing the elements in the range
`[at, len)`

. After the call, the original set will be left containing
the elements `[0, at)`

with its previous capacity unchanged.

* Panics* if

`at > len`

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

[src]

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

[src]Insert the value into the set.

If an equivalent item already exists in the set, it returns
`false`

leaving the original value in the set and without
altering its insertion order. Otherwise, it inserts the new
item and returns `true`

.

Computes in **O(1)** time (amortized average).

`pub fn insert_full(&mut self, value: T) -> (usize, bool)`

[src]

`pub fn insert_full(&mut self, value: T) -> (usize, bool)`

[src]Insert the value into the set, and get its index.

If an equivalent item already exists in the set, it returns
the index of the existing item and `false`

, leaving the
original value in the set and without altering its insertion
order. Otherwise, it inserts the new item and returns the index
of the inserted item and `true`

.

Computes in **O(1)** time (amortized average).
