GrpcCaller

dtmrs_server::grpc::client

Struct GrpcCaller 

Source 
pub struct GrpcCaller { /* private fields */ }
Expand description

gRPC 分支调用器，带 channel 缓存。

用 connect_lazy 而不是 connect：连接在首次真正发请求时才建立， 断了之后 tonic 自己重连。所以缓存里的 channel 不会因为对方重启而变成死的， 不需要额外的健康检查和淘汰逻辑。

Implementations§

Source§

impl GrpcCaller

Source

pub fn new(timeout: Duration) -> Self

Source

pub async fn call( &self, target: &GrpcTarget, gid: &str, trans_type: &str, branch_id: &str, op: &str, ) -> BranchResult

调一个 gRPC 分支。任何失败都不会返回 BranchResult::Failure —— 只有对方明确返回 ABORTED 才算业务要求回滚。
