Description

This package contains efficient general-purpose implementations of various immutable container types including sets, maps, sequences, trees, and graphs.

For a walkthrough of what this package provides with examples of common operations see the containers introduction.

The declared cost of each operation is either worst-case or amortized, but remains valid even if structures are shared.
