Functions

func Assert

func Assert(message string, cond bool)

Assert panics with the given message if cond is false.

func Check

func Check(err error)

Check panics if its argument is a non-nil error.

func Check2

func Check2[T any](a T, err error) T

Check2 panics if its second argument is a non-nil error.

func Check3

func Check3[T1, T2 any](a T1, b T2, err error) (T1, T2)

Check3 panics if its third argument is a non-nil error.

func Max

func Max[T constraints.Integer](x, y T) T

Max returns the larger of x or y.

func Min

func Min[T constraints.Integer](x, y T) T

Min returns the smaller of x or y.

func MultiLines

func MultiLines(s string) string

MultiLines formats a multiline raw string, changing:

`
	First line
		Second line
		Third line
`

to:

`First line
	Second line
	Third line`

It is intended to be called like this:

MultiLines(`
	First Line
		Second line
		Third line
`)

func Ptr

func Ptr[T any](v T) *T

Ptr returns a pointer to v.

func Reverse

func Reverse[S ~[]E, E any](s S)

Reverse reverses a slice.
