Functions

func ConvertArr

func ConvertArr[Tin any, Tout any](in []Tin, convertFunc CovertFunc[Tin, Tout]) (convertedItems []Tout, err error)

Converts all the types in

func DefaultIfEqual

func DefaultIfEqual[T comparable](in T, checkEqualTo T, defaultVal T) T

func ExecTask

func ExecTask(ctx context.Context, tasks Task) error

func ExecTasks

func ExecTasks(ctx context.Context, taskTimeout time.Duration, tasks []Task) error

ExecTasks Runs each task in a separate goroutine To set no task timeout -- set taskTimeout to 0

func Must

func Must(err error)

func MustStr2Float

func MustStr2Float[T Float](str string, bitSize int) T

func MustStr2Int

func MustStr2Int[T Int](str string, base int, bitSize int) T

func Retry

func Retry(
	ctx context.Context,
	retryTimes int,
	waitBeforeRetry time.Duration,
	exec Task,
) (success bool, errs []error)

func Str2Bool

func Str2Bool(str string) (val bool, ok bool)

func Str2Float

func Str2Float[T Float](str string, bitSize int) (T, error)

func Str2Int

func Ternar

func Ternar[T any](condition bool, ifTrue T, ifFalse T) T

func UnnilArray

func UnnilArray[T any](in []T) []T

If array is equal to nil -- will return an empty array instead

func UnnilMap

func UnnilMap[K comparable, V any](in map[K]V) map[K]V

If map is equal to nil -- will return an empty map instead

func ValOrDefaultNum

func ValOrDefaultNum[T Num](in T, defaultVal T) T

If in is 0 returns the devaultVal. Else returns in

func ValOrDefaultStr

func ValOrDefaultStr(in string, defaultVal string) string

If in is empty returns the devaultVal. Else returns in
