func ReadAll

func ReadAll(r io.Reader) ([]byte, error)

ReadAll reads all data from r and returns it as a byte slice. A successful call returns err == nil, not err == EOF. It does not treat an EOF as an error to be reported.

This function is similar to io.ReadAll, but uses a bytes.Buffer to accumulate the data, which has a more efficient growing algorithm and uses io.WriterTo if r implements it.

Example

r := strings.NewReader("The quick brown fox jumps over the lazy dog.")

b, err := ReadAll(r)
if err != nil {
	log.Fatal(err)
}

fmt.Printf("%s", b)

Output:

The quick brown fox jumps over the lazy dog.
