Method ReadFrom

protocol/bc/hash.go:110–118

ReadFrom satisfies the io.ReaderFrom interface.

(r io.Reader)

// ReadFrom satisfies the io.ReaderFrom interface.
func (h *Hash) ReadFrom(r io.Reader) (int64, error) {
	var b32 [32]byte
	n, err := io.ReadFull(r, b32[:])
	if err != nil {
		return int64(n), err
	}
	*h = NewHash(b32)
	return int64(n), nil
}

// IsZero tells whether a Hash pointer is nil or points to an all-zero
// hash.
