The underlying implementation is designed to avoid all allocations on insertion, removal, retrieval, and iteration. Allocations may still happen on insertion when the underlying storage needs to grow to accommodate newly added elements to the set. This implementation makes no guarantee as to the order of the elements stored, nor does it make guarantees that the order remains constant over time. This implementation is not thread-safe: if multiple threads access this container concurrently, and one or more threads modify the structure of the set (insertion or removal for instance), the calling code must provide the appropriate synchronization. Concurrent reads are however safe. ## Summary | ### Public constructors |
