EqHashSet

dotty.tools.dotc.util.EqHashSet
See theEqHashSet companion object
class EqHashSet[T](initialCapacity: Int, capacityMultiple: Int) extends GenericHashSet[T]

A hash set that allows some privileged protected access to its internals

Value parameters

capacityMultiple

The minimum multiple of capacity relative to used elements. The hash table will be re-sized once the number of elements multiplied by capacityMultiple exceeds the current size of the hash table. However, a table of size up to DenseLimit will be re-sized only once the number of elements reaches the table's size.

initialCapacity

Indicates the initial number of slots in the hash table. The actual number of slots is always a power of 2, so the initial size of the table will be the smallest power of two that is equal or greater than the given initialCapacity. Minimum value is 4.
