 *
 * The cvc5 C++ API.
 *
 * A brief note on how to guard API functions:
 *
 * In general, we think of API guards as a fence -- they are supposed to make
 * sure that no invalid arguments get passed into internal realms of cvc5.
 * Thus we always want to catch such cases on the API level (and can then
 * assert internally that no invalid argument is passed in).
 *
 * The only special case is when we use 3rd party back-ends we have no control
 * over, and which throw (invalid_argument) exceptions anyways. In this case,
 * we do not replicate argument checks but delegate them to the back-end,
 * catch thrown exceptions, and raise a CVC5ApiException.
 *
 * Our Integer implementation, e.g., is such a special case since we support
 * two different back end implementations (GMP, CLN). Be aware that they do
 * not fully agree on what is (in)valid input, which requires extra checks for
 * consistent behavior (see Solver::mkRealFromStrHelper for an example).
