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 |
Usage
The cargo package is available at:
Add the following piece of code to your Cargo.toml:
[dependencies]
crdt-sample = "0.1.0"
Example
use crdt_sample::{AworsetOpt, NodeId};
fn main() {
let node_id = NodeId::new(1, "addr".to_string());
let mut aworset: AworsetOpt<i32> = AworsetOpt::new(node_id);
aworset.add(1);
println!("{:?}", aworset);
// AworsetOpt { id: addr1, set: {(addr1, 1, 1)}, cc: DotContext { cc: {addr1: 1}, dc: {} } }
}
