Hello Hay, with interface{} you explicitly allow everything. Instead you may consider to restrict the accepted input in the first place - e.g. with a non-empty interface. Chris hay schrieb am Mo. 19. Nov. 2018 um 15:37: > Hi, > > I've the following example code of correct ver

[go-nuts] Error Handling Best Practice (error wrapping)

o make sure I am spotting errors correctly and checking that I am getting the correct error from the correct place is really quite clunky at the moment, if I could test that an error checker in location X was triggered by it being passed an error that would save me a lot of code. Any suggestion
