Functions ¶
func Abs ¶
func Abs[T constraints.Integer](n T) T
func AppendLineToFile ¶
func AppendUnique ¶
func AppendUnique[T comparable](slice []T, elems ...T) []T
func AssertMustError ¶
func AssertNoError ¶
func CallWithTimeout ¶
CallWithTimeout calls fun. If it does not finish in timeout period, calls onTimeout
func CatchPanicOrError ¶
func ED25519PrivateKeyFromHexString ¶
func ED25519PrivateKeyFromHexString(str string) (ed25519.PrivateKey, error)
func EqualSlices ¶
func EqualSlices[T comparable](s1, s2 []T) bool
func ForEachUniquePair ¶
func IndexOfMaximum ¶
IndexOfMaximum slice cannot be empty
func KeysFiltered ¶
func KeysFiltered[K comparable, V any](m map[K]V, cond func(k K) bool) []K
func KeysFilteredByValues ¶
func KeysFilteredByValues[K comparable, V any](m map[K]V, cond func(k K, v V) bool) []K
func KeysSorted ¶
func KeysSorted[K comparable, V any](m map[K]V, less func(k1, k2 K) bool) []K
func MakeErrFuncForPrefix ¶
func MakeRange ¶
func MakeRange[T constraints.Integer](from, toIncl T) []T
func MustErrorWith ¶
func MustLastElement ¶
func MustLastElement[T any](sl []T) T
func MustPrivateKeyFromHexString ¶
func MustPrivateKeyFromHexString(k string) ed25519.PrivateKey
func PercentString ¶
func PrivateKeyFromHexString ¶
func PrivateKeyFromHexString(k string) (ed25519.PrivateKey, error)
func PurgeFilesInDirectory ¶
func PurgeSlice ¶
PurgeSlice filters elements on the same underlying array Element remains in the array only if 'filter' function returns true The elements of the array which are not covered by slice are nullified. This may be important when slice contains pointers, which, in turn, may lead to hidden memory leak because GC can't remove them
func RandomElements ¶
RandomElements selects n random elements from a slice, which has more elements than n
func RandomNOutOfMPractical ¶
RandomNOutOfMPractical tries to generate n different random numbers from [0:m]. Only makes 2 * n attempts, so result may be less than n numbers
func RequirePanicOrErrorWith ¶
func RunWrappedRoutine ¶
func StringsLess ¶
func ValuesFiltered ¶
func ValuesFiltered[K comparable, V any](m map[K]V, filter func(v V) bool) []V
Types ¶
type Number ¶
type Number interface {
constraints.Float | constraints.Integer | time.Duration
}
