Functions

func ReadFull

func ReadFull(r BufferedReader, buf []byte) (int, error)

ReadFull reads exactly len(buf) bytes from r into buf, like io.ReadFull, but without heap allocations. It uses Peek to access the buffered data directly, copies it into buf, then discards the consumed bytes. If an error occurs, discard is not called and the buffer is left unchanged.

Types

type BufferedReader

type BufferedReader interface {
	Peek(n int) ([]byte, error)
	Discard(n int) (discarded int, err error)
}

BufferedReader is an interface for readers that support peeking into an internal buffer, like bufio.Reader.
