Accessing error code from returned error

[bendikro]

When performing a CreateDatabase where the database already exists, the database returns error code 1207 (https://docs.arangodb.com/3.0/Manual/Appendix/ErrorCodes.html, ERROR_ARANGO_DUPLICATE_NAME).

This error code is wrapped in a numberedError at https://github.com/solher/arangolite/blob/v2.0.1/database.go#L207

However, at the next step, the numberedError is wrapped in a statusCodedError at https://github.com/solher/arangolite/blob/v2.0.1/database.go#L213

The statusCodedError is what is returned by Send.

My question is how should the error code be accessed?

HasErrorNum will not work, since it requires a numberedError as input, and casting to statusCodedError to access the error attribute doesn't work, since statusCodedError is not exported.

Current result of arangolite.HasStatusCode(err) is 409, but arangolite.HasErrorNum(e_status, 1207) gives false.

Well the answer is quite simple. I just messed up my wrapping :)
Could you try again with the tip? It should be fixed now.
I also added some GetErrorNum and GetStatusCode functions to allow better debugging.

Hi @solher

Look at these tests: https://github.com/bendikro/arangolite/blob/master-error-tests/errors_test.go

Are they supposed to pass?

I still don't understand how I can access the error number when the numberedError is wrapped inside a statusCodedError.
