crdts_derive

Usage

Add the dependency

Add the crdts and crdts_derive dependency to Cargo.toml:

toml [dependencies] crdts = "7.3" crdts_derive = "7.3"

Custom CRDT struct

```rust use crdts::{CmRDT, GCounter, Map, Orswot}; use crdts_derive::crdt;

[crdt(u64)]

[derive(Default, Debug)]

pub struct Data { a: Orswot, b: Map, u64>, u64>, c: Orswot, u64>, d: GCounter, }

[test]

fn test() { let mut controller = Data::default(); let actor = 1; let counter = 1; let dot = crdts::Dot::new(actor, counter); let op1 = controller.a.add( format!("{actor}-{counter}"), controller.a.read().deriveaddctx(actor.to_string()), );

let add_ctx = controller.b.read_ctx().derive_add_ctx(actor);
let op2 = controller
    .b
    .update(actor, add_ctx, |v, a| v.add(vec![actor as u8; 20], a));

let op3 = controller.c.add(
    vec![actor as u8; 20],
    controller.c.read().derive_add_ctx(actor),
);

let op4 = controller.d.inc(actor);
controller.apply(DataCrdtOp {
    dot,
    a_op: Some(op1),
    b_op: Some(op2),
    c_op: Some(op3),
    d_op: Some(op4),
});
println!("{:#?}", controller);

}

```
