how to retry request by custom policy

[xj524598]

pseudo code：
loop {
let resp=client.execute(request);
//custom policy
if current_time="2023-11-11"{
continue;
}
break;
}
if want retry like this,request must clone, request has no clone method

even request has clone() method, i think it may cost expansive.
if we can use send_request method,we can get request from ClientError
