      tx_exception(const tx_exception& other) transaction_safenoexcept;
      		 (4)(TM TS)
      1-3) Constructs the exception object withwhat_arg as explanatory string that can be accessed throughwhat() andvalue as the object that can be accessed throughget().
      4) Copy constructor. If*this andother both have dynamic typestd::tx_exception<T> thenstd::strcmp(what(), other.what())==0.

      Parameters

      value - payload object
      what_arg - explanatory string
      other - another exception object to copy

      Exceptions

      1-3) May throw implementation-defined exceptions.

      tx_exception& operator=(const tx_exception& other) transaction_safenoexcept;
      		(TM TS)

      Parameters

      other - another exception object to assign with

      Return value
