1//! > **Metamodel - A Rust Library for Abstract State Machine Modeling**
2//!
3//! See the code below for an example of how to create a Petri-net model using the `pflow_metamodel` library.
4//!
5//! Also see: [Macro pflow_metamodel::pflow_dsl](macro.pflow_dsl.html) for creating models using an internal rust DSL rather than json.
6//! ```
7//! use pflow_metamodel::*;
8//!
9//! let model: Model = pflow_json!{{
10//!    "modelType": "petriNet",
11//!    "version": "v0",
12//!    "places": {
13//!      "place0": { "offset": 0, "capacity": 3, "x": 100, "y": 180 }
14//!    },
15//!    "transitions": {
16//!      "txn0": { "role": "role0", "x": 20, "y": 100 },
17//!      "txn1": { "role": "role0", "x": 180, "y": 100 },
18//!      "txn2": { "role": "role0", "x": 20, "y": 260 },
19//!      "txn3": { "role": "role0", "x": 180, "y": 260 }
20//!    },
21//!    "arcs": [
22//!      { "source": "txn0", "target": "place0" },
23//!      { "source": "place0", "target": "txn1", "weight": 3 },
24//!      { "source": "txn2", "target": "place0", "weight": 3, "inhibit": true },
25//!      { "source": "place0", "target": "txn3", "inhibit": true }
26//!    ]
27//! }};
28//!
29//! let state = model.vm.initial_vector();
30//! assert_eq!(state, vec![0]);
31//! let res = model.vm.transform(&state, "txn0", 1);
32//! assert!(res.ok);
33//! assert_eq!(state, vec![0]); // input state is _not_ mutated
34//! assert_eq!(res.output, vec![1]);
35//! let t = model.net.transitions.get("txn0");
36//! assert!(t.is_some());
37//! ```
38//!
39//! - Provides a DSL-driven framework for modeling and simulating Petri-nets, wf-nets, and DFAs.
40//! - State machine data types are executed as a [Vector Addition State Machine (VASM)](https://en.wikipedia.org/wiki/Vector_addition_system).
41//! - Data models are viewable / shareable in browsers by using [https://pflow.dev](https://pflow.dev/p/zb2rhkizUC1o2JuvgwhbH1XrLZkdK8x66pP1KR7sWAEw9c5FE/) JSON format.
42//! - Models can be compressed and shared as base64 encoded blobs.
43//! - Models can be consistently hashed and shared as CIDs.
