Functions

func CoarseTimeNow

func CoarseTimeNow() time.Time

CoarseTimeNow returns the current time truncated to the nearest second.

Deprecated: This is slower than calling time.Now() directly. This is now time.Now().Truncate(time.Second) shortcut.

func CopyZeroAlloc

func CopyZeroAlloc(w io.Writer, r io.Reader) (int64, error)

func CreateFixedBytes

func CreateFixedBytes(bodySize int) []byte

func Round2

func Round2(n int) int

Types

type FlushWriter

type FlushWriter struct {
	Wf writeFlusher
	Bw *bufio.Writer
}

func (*FlushWriter) Write

func (w *FlushWriter) Write(p []byte) (int, error)

type NoCopy

type NoCopy struct{} //nolint:unused

Embed this type into a struct, which mustn't be copied, so `go vet` gives a warning if this struct is copied.
