package handlers

import "errors"

// Sentinel errors the handlers branch on with errors.Is to decide which
// problem response a failure deserves. They exist to separate a client's
// mistake from a server fault where the code that detects both is the same
// code — the repositories return plain errors, so without these every failure
// out of a lookup would have to be answered as a 500.

// errUnknownCatagoryID reports that a submitted category id is not in the
// category table. It is kept distinct from the error the lookup itself
// returns because the two are not the same kind of failure: an id nobody has
// is the client's mistake and answers 404, while a lookup that could not run
// is the server's and answers 500.
var errUnknownCatagoryID = errors.New("unknown catagory id")
