Hi, @Xuanwo, is there anything else should be added in this PR.

[Xuanwo]

Please provide detailed descriptions for each const so we can understand their meanings.

[Xuanwo]

The error messages we provide should clarify what went wrong and guide users on how to fix the issue. Please ensure that the errors are understandable to users. Initially, we can return Unexpected(source).

It's ready for review now.

There are many things to polish, but I think we should give it a go.
