Sample CRDTs

A repository containing some CRDTs implementations in Rust.

| CRDT | Type | Tests | | --- | --- | --- | | [Aworset] Add-Wins Observed Remove Set| State-Based | aworset.rs | | [Aworset Optimized] Add-Wins Observed Remove Set | State-Based | --- | | [GCounter] Grow-Only Counter| State-Based | -- | | [PnCounter] Positive-Negative Counter| State-Based | -- | | [MvReg] Multi-Value Register [on progress]| State-Based | --- | --- |

Auxiliary structures

Some auxiliary structures were built to create some CRDTs:

| Name | Tests | Explanation | Reference | | --- | --- | --- | --- | | DotContext | dotcontext.rs | Bartosz Sypytkowski Blog | delta-enabled-crdts |
