Function MaskFrameWith

frame.go:328–334

MaskFrameWith masks frame with given mask and returns frame with masked payload and Mask header's field set. Note that it copies f payload to prevent collisions. For less allocations you could use MaskFrameInPlaceWith or construct frame manually.

(f Frame, mask [4]byte)

// Note that it copies f payload to prevent collisions.
// For less allocations you could use MaskFrameInPlaceWith or construct frame manually.
func MaskFrameWith(f Frame, mask [4]byte) Frame {
	// TODO(gobwas): check CopyCipher ws copy() Cipher().
	p := make([]byte, len(f.Payload))
	copy(p, f.Payload)
	f.Payload = p
	return MaskFrameInPlaceWith(f, mask)
}

// MaskFrameInPlace masks frame and returns frame with masked payload and Mask
// header's field set.
