Struct OwnedExecutionEngine 

pub struct OwnedExecutionEngine<S: WorkflowState> { /* private fields */ }

拥有 State 所有权的执行引擎 — 用于 Parallel 分支等需要独立 State 的场景。

Implementations

impl<S: WorkflowState> OwnedExecutionEngine<S>

pub fn new( state: S, stream: Option<Arc<dyn StreamSink>>, cancel: CancellationToken, ) -> Self

创建拥有 State 所有权的 Engine（用于 Parallel 分支等场景）。

pub fn into_state(self) -> S

消费并返回最终状态。

pub fn state(&self) -> &S

pub fn state_mut(&mut self) -> &mut S

pub fn cancel_token(&self) -> &CancellationToken

pub fn stream_sink(&self) -> Option<Arc<dyn StreamSink>>

pub fn commit(&mut self)
