Crate bpmn_engine 

BPMN Engine

BPMN 2.0 execution engine for Rust.

This crate provides a high-performance, type-safe BPMN 2.0 execution engine that supports BPMN 2.0 JSON format as standard I/O.

Design Principles

• Activity/Capability-based design: Following DoDAF v2 DM2 principles
• Type safety: Leveraging Rust’s type system
• Extensibility: Support for custom tasks and listeners
• Future-ready: Designed for GraphQL API and persistence layer integration

Example

use bpmn_engine::{Engine, ProcessDefinition};

let engine = Engine::new();
let definition = ProcessDefinition::from_json(r#"
{
  "id": "process1",
  "name": "Example Process",
  "elements": []
}"#)?;

let instance = engine.start_process(definition, None).await?;
