Function appendArray

array.go:694–712

appendArray appends rv to the buffer, returning the extended buffer and the delimiter used between elements. Returns an error when n <= 0 or rv is not a reflect.Array or reflect.Slice.

(b []byte, rv reflect.Value, n int)

//
// Returns an error when n <= 0 or rv is not a reflect.Array or reflect.Slice.
func appendArray(b []byte, rv reflect.Value, n int) ([]byte, string, error) {
	var del string
	var err error

	b = append(b, '{')

	if b, del, err = appendArrayElement(b, rv.Index(0)); err != nil {
		return b, del, err
	}

	for i := 1; i < n; i++ {
		b = append(b, del...)
		if b, del, err = appendArrayElement(b, rv.Index(i)); err != nil {
			return b, del, err
		}
	}

	return append(b, '}'), del, nil
}

// appendArrayElement appends rv to the buffer, returning the extended buffer
// and the delimiter to use before the next element.
