lattice_crdt

Umbrella package for Lattice CRDTs: counters, registers, sets, maps, and causal core types.

Install this package when you want the full Lattice CRDT toolkit. For smaller dependency graphs, install the individual packages directly.

Installation

gleam add lattice_crdt

Packages included

Package	Provides
`lattice_core`	Replica IDs, version vectors, and dot contexts.
`lattice_counters`	Grow-only and positive-negative counters.
`lattice_registers`	Last-writer-wins and multi-value registers.
`lattice_sets`	Grow-only, two-phase, and observed-remove sets.
`lattice_maps`	Last-writer-wins maps, observed-remove maps, and CRDT dispatch.

Quick example

import lattice_core/replica_id
import lattice_counters/g_counter

pub fn main() {
  let counter =
    g_counter.new(replica_id.new("node-a"))
    |> g_counter.increment(1)

  g_counter.value(counter)
  // -> 1
}

Notes

This package reuses the public modules from the individual Lattice packages.
Import modules from their package-specific paths, such as lattice_counters/g_counter or lattice_sets/or_set.
All CRDT packages support deterministic merge semantics and JSON serialization.
Many mutators also expose delta-state variants for efficient incremental replication.
