Functions

func Colored

func Colored(color string, a ...any) string

func Contains

func Contains[T comparable](slice []T, item T) bool

func DurationRoundBy

func DurationRoundBy(duration time.Duration, n int64) time.Duration

func Flatten

func Flatten[T any](nested [][]*T) []*T

func NumLen

func NumLen[T Number](n T) T

func PrettyJSONMarshal

func PrettyJSONMarshal(v interface{}, maxItems int, prefix, indent string) []byte

func PrintAndExit

func PrintAndExit(message string)

func PrintErr

func PrintErr(err error)

func PrintErrAndExit

func PrintErrAndExit(err error)

func PrintfC

func PrintfC(color string, format string, a ...any)

func PrintlnC

func PrintlnC(color string, a ...any)

func RandomValueCycle

func RandomValueCycle[Value any](values []Value, localRand *rand.Rand) func() Value

RandomValueCycle returns a function that cycles through the provided slice of values in a random order. Each call to the returned function will yield a value from the slice. The order of values is determined by the provided random number generator.

The returned function will cycle through the values in a random order until all values have been returned at least once. After all values have been returned, the function will reset and start cycling through the values in a random order again. The returned function isn't thread-safe and should be used in a single-threaded context.
