Functions

func Copy

func Copy(src []byte) []byte

Copy will return a new byte slice with a copy of 'src's contents

Types

type StringWriter

type StringWriter interface {
	Write([]byte) (int, error)
	WriteByte(byte) error
	WriteRune(r rune) (int, error)
	WriteString(s string) (int, error)
}

StringWriter defines an abstract set of functions used when writing strings. bytes.Buffer, bufio.Writer & strings.Builder all implement this interface.

Although these methods expose the standard Go writer semantics of returning errors, users of StringWriter generally do not check for errors. Constructors of this interface should arrange to detect errors externally if needed (e.g. by checking the result of Flush on a bufio.Writer).
