Inspect Your Errors Unwrapping Go Errors For Fun And Profit Dev Now let's talk about the various ways to unwrap and inspect errors. I've talked about how to wrap errors in go before (here and here). now let's talk about the various ways to unwrap and inspect errors.

Wrapping Errors The Right Way R Golang To support wrapping, fmt.errorf now has a %w verb for creating wrapped errors, and three new functions in the errors package ( errors.unwrap, errors.is and errors.as) simplify unwrapping and inspecting wrapped errors. The standard library offers errors.is () to traverse wrapped errors. it walks the error tree and returns true if any error in the chain matches the target error value:. It is also possible to check if a given error exists anywhere in the chain thanks to the errors.is() and errors.as() functions. see the examples below for details on how to wrap, unwrap, and test for error types. I've talked about how to wrap errors in go before. but what about doing the reverse? in my latest video, i walk you through several techniques for error inspection, and show the power of error.

I've talked about how to wrap errors in go before. but what about doing the reverse? in my latest video, i walk you through several techniques for error inspection, and show the power of error. Errors.is() looks in the error chain to see if we have an underlying error embedded there, whose value equals the value of errbadinput so in a nutshell, use errors.is() instead of err==errmyerr to check if the value of an error is equal to a sentinel error value.
