func NewFunc(f func(ctx interface{})) func(ctx interface{}) bool NewFunc returns stackless wrapper for the function f. Unlike f, the returned stackless wrapper doesn't use stack space on the goroutine that calls it. The wrapper may save a lot of stack space if the following conditions are met: - f doesn't contain blocking calls on network, I/O or channels; - f uses a lot of stack space; - the wrapper is called from high number of concurrent goroutines. The stackless wrapper returns false if the call cannot be processed at the moment due to high load.

func NewWriter(dstW io.Writer, newWriter NewWriterFunc) Writer NewWriter creates a stackless writer around a writer returned from newWriter. The returned writer writes data to dstW. Writers that use a lot of stack space may be wrapped into stackless writer, thus saving stack space for high number of concurrently running goroutines.
