This repo contains tests for otto. otto enables any boring Rust data structure (without Rc, RefCell etc.) to be used as a replicated data type. It supports achieving convergence via multiple approaches, including:

• Wrapping with Crdt<T> to leverage operation-based CRDT techniques.
• Methods insert_and_rebase_forward, insert_and_rebase_back and converge to leverage OT techniques with a synchronising server.

It also supports combining these approaches to synchronise a mix of clients using both CRDT and OT techniques.

• Minimal bookkeeping (no timestamps, IDs or similar)
• Rich set of data types (e.g. RichText) and operations (e.g. sort and group_by operations on List<T>)
• Composability (support arbitrary nesting of types, e.g. List<(u64, List<u8>)>)
• Differential dataflow support
• Performance, sufficient for overhead to be negligible in real-world use (within ~1 OoM of Diamond types)
• Achieve the strongest known useful properties (e.g. convergence and inverse properties)
