Overview ¶

Package errors implements functions for advanced error handling.

Errors in this package contain a message, a cause (an error that caused this error) and an attachment (any interface{}). Errors also contain information about the program location where they were created.

Errors can be printed using the fmt.Printf verbs %s, %q, %x, %X, %v. In particular the %+v format will print an error complete with its stack trace.
