QUESTION: How does one incorporate this with behaviors?
ntucker opened this issue · comments
In https://dave.cheney.net/2016/04/27/dont-just-check-errors-handle-them-gracefully there is talk about having interfaces for certain types of checks, but how does one actually build a new error with these interfaces and also use the cool error types provided here?
One might think composing the types would work, but this package doesn't make its types public.
The intention is you start with your own error type which implements the behaviour you want to assert for, then use Wrap or With to annotate it during the error path, at the point you want to test for the original behaviour, use cause to undo all those layers of annotations and recover the original error.
