CRDT

Initial API Release

• Multiple well-known CRDT types included:
  • GCounter, PNCounter, GSet, ORSet, ORMap, and List
• Documentation hosted at Swift Package Index
• All included CRDT implementations support whole-instance merging and delta-state replication and merging.
• APIs for merging include merged(:_) which implicitly makes a copy, and merging(:_) which modifies an in-place struct.
• Corrupted history is identifier and thrown as an error, relevant for ORSet, ORMap, and List types.
• Project includes basic benchmarks, with results available through the GitHub repo.
• extended conformances for CRDT types, when underlying (and ActorID) types support it: Codable, Hashable, Equatable, and Sendable

Initial alpha release.

The pre-release includes an initial implementation, API, and documentation for the raw CRDT data types:

• GCounter
• PNCounter
• LWWRegister
• GSet
• ORSet

The pre-release is intended for feedback on API usage, and should not be considered stable.
The delta-state merge methods are set to asynchronous, and both an ORMap and an actor-based replicator wrapper is still pending as of this release.

To use this release, add the following dependency to your Package.swift:

.package(url: "https://github.com/heckj/CRDT.git", from:"0.5.0-alpha1")
