Annotate errors

[ferhatelmas]

to provide more context to the users.

pkg/errors could be leveraged.

[tbarbugli]

do you have an example?

[ferhatelmas]

For example, client has an error in Do, the caller of Do just returns the error but it could do Wrap or WithMessage to signal where that error had happened.

https://github.com/cockroachdb/errors is another package that can do this job and is more future proof than pkg/errors comparatively (by having go1.13 helpers)

Why not use the fmt.Errorf %w directive? 😃

[ferhatelmas]

Yes, it's a good idea but I'm not sure about the target go versions. Above packages would work in old versions but %w directive requires 1.13 and above.

Also, I believe 1.13 adaptation will be much slower compared to previous versions due to modules, GOPROXY and GOPRIVATE.

I've heard about cocroachdb/errors library, it looks very great, but I've never used it before.
pkg/errors was awesome for that 👍
