Review Comment:
With your design, the sender needs to judge the response as follows:
```c++
if (rpc == ok) {
if ( resp.err == ok) {
if (resp.checkpoint_err == ok) {
/** if you define `more clear err code as you say`, maybe
need:**/
/** if (err_a == ...) {
if (err_b == ...)
}
}
}
}
```
This logic is also redundant. don't suggest this design, you can refer the
origin rpc defination, I think the origin is elegant
