stateless:转到用于创建状态机的库

无状态 直接在Go代码中创建状态机和基于轻量级状态机的工作流： phoneCall := stateless . NewStateMachine ( stateOffHook ) phoneCall . Configure ( stateOffHook ). Permit ( triggerCallDialed , stateRinging ) phoneCall . Configure ( stateRinging ). OnEntryFrom ( triggerCallDialed , func ( _ context. Context , args ... interface {}) error { onDialed ( args [ 0 ].( string )) return nil }). Permit ( triggerCallConnected
