Method read2buf

decoder.go:89–98

read2buf reads exactly n bytes from the reader dec.in into the buffer dec.buf to reduce memory allocs. The buffer grows automatically.

(n int)

// to reduce memory allocs.
// The buffer grows automatically.
func (dec *decoder) read2buf(n int) {
	if cap(dec.buf) < n {
		dec.buf = make([]byte, n)
	} else {
		dec.buf = dec.buf[:n]
	}
	if _, err := io.ReadFull(dec.in, dec.buf); err != nil {
		panic(err)
	}
}

// decodeU decodes uint32 obtained from the reader dec.in.
// The goal is to reduce memory allocs.
