func ContextWithNewCancel(parent context.Context, done <-chan struct{}) context.Context

ContextWithNewCancel replaces the parent cancellation (if any) with the given one, while preserving the embedded values.

func ContextWithTimeout(
	parent context.Context,
	clock clockwork.Clock,
	timeout time.Duration,
) (context.Context, context.CancelFunc)

func IsPermanent(err error) bool

func MakeChanInfCap[T any](expectedCap int) (<-chan T, chan<- T)

MakeChainInfCap simulates a channel with infinite capacity. This will never block the sender and grow an internal buffer if necessary.

Close the input channel when finished, to free resources.
