for some statuses there are already premade methods (like there is one for
Ok())
but apart from that, it depends how they are being usedim not taling about http status code but rather just errors in general.
lets say i got a endpoint for registering a user. but it first checks if the username isnt already taken.
how do i best return that error in case the username is already taken?
There are many way to handle that.
