Expand description
VCF record IDs (ID
).
Methods from Deref<Target = IndexSet<Id>>
Returns true if the set contains no elements.
Computes in O(1) time.
Return an iterator over the values of the set, in their order
Remove all elements in the set, while preserving its capacity.
Computes in O(n) time.
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.
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.
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
.
Reserve capacity for additional
more values.
Computes in O(n) time.
Shrink the capacity of the set as much as possible.
Computes in O(n) time.
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).
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).

Adds a value to the set, replacing the existing value, if any, that is equal to the given one. Returns the replaced value.
Computes in O(1) time (average).
Remove the value from the set, and return true
if it was present.
NOTE: This is equivalent to .swap_remove(value)
, if you want
to preserve the order of the values in the set, use .shift_remove(value)
.
Computes in O(1) time (average).
Remove the value from the set, and return true
if it was present.
Like Vec::swap_remove
, the value is removed by swapping it with the
last element of the set and popping it off. This perturbs
the position of what used to be the last element!
Return false
if value
was not in the set.
Computes in O(1) time (average).
Remove the value from the set, and return true
if it was present.
