Pure.Collections.Generic

Generic collection types for the Pure ecosystem — immutable-friendly collections backed by IDeterminedHash equality.

Overview

Pure.Collections.Generic provides collection types designed to integrate with the IDeterminedHash equality model. Each collection uses EqualityComparerByDeterminedHash as its default equality comparer, enabling content-addressed lookups over any type that implements IDeterminedHash.

Types

Type	Description
Dictionary<TKey, TValue>	Hash map keyed by IDeterminedHash equality
Set<T>	Hash set with IDeterminedHash membership checks
Array<T>	Immutable array wrapper over IDeterminedHash elements
OrderedDictionary<TKey, TValue>	Insertion-ordered dictionary with IDeterminedHash keys
Lookup<TKey, TElement>	Multi-value lookup grouped by IDeterminedHash keys
EqualityComparerByDeterminedHash	IEqualityComparer<T> using IDeterminedHash byte sequences

All types live in the Pure.Collections.Generic namespace.

Design Principles

• Hash-based equality — collections compare elements by their IDeterminedHash byte sequences, not by object.GetHashCode().
• AOT-compatible — no reflection; all generics are constrained at compile time.

Dependencies

• Pure.HashCodes.Abstractions — IDeterminedHash interface
