func Copy(r io.Reader, w io.Writer, c CopyConfig) (e error)

close by yourself

watch out uint64(c.MaxLoop*c.BytePerLoop) overflow

func RW2Chan(r io.ReadCloser, w io.WriteCloser) (rc, wc chan []byte)

no close rc any time you can close wc, r, w.

func WithCtxCopy(ctx context.Context, callTree string, copybuf []byte, to time.Duration, w io.Writer, r io.Reader, panicf ...func(s string)) error

close reader by yourself

to avoid writer block after ctx done, you should close writer after ctx done

call Close() after writer fin

func WithCtxTO(ctx context.Context, callTree string, to time.Duration, w io.Writer, r io.Reader, panicf ...func(s string)) io.ReadWriteCloser

close reader by yourself

to avoid writer block after ctx done, you should close writer after ctx done

call Close() after writer fin
