Advance

Enum Advance 

Source
pub enum Advance {
    Call {
        index: usize,
        op: BranchOp,
    },
    Finish(GlobalStatus),
    Wait,
    RunWorkflow,
}
Expand description

推进全局事务后,状态机给出的下一步指令

Variants§

§

Call

调这个分支

Fields

§index: usize
§

Finish(GlobalStatus)

全部完成,落终态

§

Wait

有分支 Ongoing/Unknown,本轮到此为止,等下次 cron

§

RunWorkflow

跑一遍用户的 workflow 函数(只有 TransType::Workflow 会出现)。

单独一个变体而不是复用 Call:workflow 的正向走向是用户函数决定的, 不是状态机决定的。混进 Call 会让人以为这里也能算出「下一个分支是谁」。
