//@ compile-flags: --diagnostic-width=20 --error-format=json

// This test checks that `-Z output-width` effects the JSON error output by restricting it to an
// arbitrarily low value so that the effect is visible.

                    //~| NOTE expected `()`, found integer
                    //~| NOTE expected due to this
