func (*BitArray) String ¶

func (bA *BitArray) String() string

String returns a string representation of BitArray: BA{<bit-string>}, where <bit-string> is a sequence of 'x' (1) and '_' (0). The <bit-string> includes spaces and newlines to help people. For a simple sequence of 'x' and '_' characters with no spaces or newlines, see the MarshalJSON() method. Example: "BA{_x_}" or "nil-BitArray" for nil.
