Functions

func BeTrue

func BeTrue(b bool)

BeTrue panic if the b is not true.

Use that function only for static initialization, test code, or statemants that "can't" be false. When in doubt, don't.

func BeZero

func BeZero[T comparable](v T)

BeZero panics if argument has non-zero value.

Use that function only for static initialization, test code, or code that "can't" fail. When in doubt, don't.

func NoError

func NoError(err error)

NoError panics if the error is not nil.

Use that function only for static initialization, test code, or code that "can't" fail. When in doubt, don't.

func NotBeZero

func NotBeZero[T comparable](v T)

NotBeZero panics if argument has zero value.

Use that function only for static initialization, test code, or code that "can't" fail. When in doubt, don't.

func NotFail

func NotFail[T any](res T, err error) T

NotFail panics if the error is not nil, returns res otherwise.

Use that function only for static initialization, test code, or code that "can't" fail. When in doubt, don't.
