Struct Driver

Source

pub struct Driver {
    pub store: Store,
    pub http: Client,
    pub owner: String,
    pub lease: i64,
    pub registry: Arc<Registry>,
    pub grpc: GrpcCaller,
    pub workflows: Arc<WorkflowRegistry>,
}

Fields§

§store: Store§http: Client§owner: String§lease: i64

租约时长（秒）。持租约的实例崩了，这么久之后别的实例接手

§registry: Arc<Registry>

进程内分支注册表。嵌入式模式用，纯 HTTP 部署时是空表

§grpc: GrpcCaller

gRPC 分支调用器（带 channel 缓存）

§workflows: Arc<WorkflowRegistry>

workflow 函数注册表。跟 registry 一样，纯 HTTP 部署时是空表

Implementations§

Source §

impl Driver

Source

pub fn new(store: Store, owner: String) -> Self

Source

pub fn with_registry(self, r: Arc<Registry>) -> Self

挂上进程内分支注册表 —— 嵌入式模式的入口

Source

pub fn with_workflows(self, w: Arc<WorkflowRegistry>) -> Self

挂上 workflow 函数注册表

Source

pub async fn run_forever(self, tick: Duration)

常驻循环：抢一个到期事务推一下，没活就睡

Source

pub async fn process(&self, g: &GlobalRow) -> Result<()>

推进一个全局事务，直到它落终态或需要等待。

可以被重复调用（崩溃恢复就靠这个）—— 分支的幂等由客户端屏障保证。
