Function writeInt

expfmt/text_create.go:502–508

writeInt is equivalent to fmt.Fprint with an int64 argument but uses strconv.AppendInt with a byte slice taken from a sync.Pool to avoid allocations.

(w enhancedWriter, i int64)

// strconv.AppendInt with a byte slice taken from a sync.Pool to avoid
// allocations.
func writeInt(w enhancedWriter, i int64) (int, error) {
	bp := numBufPool.Get().(*[]byte)
	*bp = strconv.AppendInt((*bp)[:0], i, 10)
	written, err := w.Write(*bp)
	numBufPool.Put(bp)
	return written, err
}

// writeName writes a string as-is if it complies with the legacy naming
// scheme, or escapes it in double quotes if not.
