Instance Property

underestimatedCount

A value less than or equal to the number of elements in the sequence, calculated nondestructively.

Declaration

var underestimatedCount: Int { get }

Discussion

The default implementation returns 0. If you provide your own implementation, make sure to compute the value nondestructively.

Complexity: O(1), except if the sequence also conforms to Collection. In this case, see the documentation of Collection.underestimatedCount.
