CommandDeliveryPolicy

Struct CommandDeliveryPolicy 

Source
pub struct CommandDeliveryPolicy {
    pub max_retries: u32,
}
Expand description

业务作用:限制同一 command 的普通瞬态重试次数,不影响结果不确定分支的持续收敛。

Fields§

§max_retries: u32

普通失败可重投的最大序号。

Implementations§

Source§

impl CommandDeliveryPolicy

Source

pub fn decide( self, error: &Error, retry_attempt: u32, ) -> CommandDeliveryDisposition

业务作用:结合失败类别与本次普通重试序号裁决 command 投递动作。

参数说明:error 是完整错误链,retry_attempt 是从一开始的普通失败序号。

返回:确定性合同错误立即隔离,普通失败超预算后隔离,关键事务阶段持续保留。
