bpm-core
Core semantics of the BPM engine: process, token, node types, events, and saga.
Role
- Pure logic, no I/O. This crate defines data structures and state transitions only.
- ProcessDefinition, ProcessInstance, Token, NodeType (Start, End, UserTask, ServiceTask, ExternalTask, gateways).
- EngineEvent and event-driven transitions.
- Saga and compensation ordering.
Usage
Used by bpm-runtime, bpm-storage, bpm-bpmn, and the REST server. Do not change casually.
