pub struct Ids(/* private fields */);

VCF record IDs (ID).

Methods from Deref<Target = IndexSet<Id>>

pub fn capacity(&self) -> usize

Return the number of elements the set can hold without reallocating.

This number is a lower bound; the set might be able to hold more, but is guaranteed to be able to hold at least this many.

Computes in O(1) time.

pub fn hasher(&self) -> &S

Return a reference to the set’s BuildHasher.

pub fn len(&self) -> usize

Return the number of elements in the set.

Computes in O(1) time.

pub fn is_empty(&self) -> bool

Returns true if the set contains no elements.

Computes in O(1) time.

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

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

pub fn clear(&mut self)

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

Computes in O(n) time.

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

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>,

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) -> IndexSet<T, S>

where S: Clone,

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 reserve(&mut self, additional: usize)

Reserve capacity for additional more values.

Computes in O(n) time.

pub fn reserve_exact(&mut self, additional: usize)

Reserve capacity for additional more values, without over-allocating.

Unlike reserve, this does not deliberately over-allocate the entry capacity to avoid frequent re-allocations. However, the underlying data structures may still have internal capacity requirements, and the allocator itself may give more space than requested, so this cannot be relied upon to be precisely minimal.

Computes in O(n) time.

pub fn try_reserve(&mut self, additional: usize) -> Result<(), TryReserveError>

Try to reserve capacity for additional more values.

Computes in O(n) time.

pub fn try_reserve_exact( &mut self, additional: usize ) -> Result<(), TryReserveError>

Try to reserve capacity for additional more values, without over-allocating.

Unlike try_reserve, this does not deliberately over-allocate the entry capacity to avoid frequent re-allocations. However, the underlying data structures may still have internal capacity requirements, and the allocator itself may give more space than requested, so this cannot be relied upon to be precisely minimal.

Computes in O(n) time.

pub fn shrink_to_fit(&mut self)

Shrink the capacity of the set as much as possible.

Computes in O(n) time.

pub fn shrink_to(&mut self, min_capacity: usize)

Shrink the capacity of the set with a lower limit.

Computes in O(n) time.

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

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

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

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).
