- How to use Golang's error wrapper?
- In Golang, error wrappers allow you to create new errors by appending contextual information to the original error. This can be used to unify the types of errors thrown by different libraries or components, simplifying debugging and error handling. The steps are as follows: Use the errors.Wrap function to wrap the original errors into new errors. The new error contains contextual information from the original error. Use fmt.Printf to output wrapped errors, providing more context and actionability. When handling different types of errors, use the errors.Wrap function to unify the error types.
