Simplee |> Euklid

Rust crate for the CRDTs.

Dot

The Dot is implementing a marked version. ```rust extern crate euklid; use euklid::Dot;

// Create a dot for actor Alice. let mut dot = Dot::new("Alice".tostring(), 0); // Increment the dot. dot.applyinc(); ``` More examples can be found in the example file.

Vector Clock

The VClock is implementing a vector clock. ```rust extern crate euklid; use euklid::{Dot, VClock};

// Create a vclock and increment the counter for user A. let mut a = VClock::new();

// Increment the counter for actor A a.apply(a.inc_op("A"));

// Increment the counter for actor B a.apply(a.inc_op("B")); ```

More examples can be found in the example file.

G-Counter

The GCounter is implementing a grow-only counter. ```rust xtern crate euklid; use euklid::{Dot, GCounter};

// Create a vclock and increment the counter for user A. let mut a = VGounter::new();

// Increment the counter for actor A a.apply(a.inc_op("A"));

// Increment the counter for actor B a.apply(a.inc_op("B"));

// Increase the counter for actor A by 5 a.apply(a.step_op("A", 5)); ``` More examples can be found in the example file.
