Missing Unwrap function for internal bolt errors #631
Description
We are using latest driver v5, and when context is cancelled, the error returned from the ExecuteRead or similar function is ConnectionReadCanceled etc. It is in internal package (neo4j/internal/errorutil/bolt.go), so we cannot try to cast to the type.
And because none of the error types below implements Unwrap, the errors.Is() will not succeed either.
- ConnectionReadTimeout
- ConnectionWriteTimeout
- ConnectionReadCanceled
- ConnectionWriteCanceled
It should be sufficient to implement Unwrap method. No need to expose errors in public API.
