this and the input.
predicate::enable_make_error_code_compatible_conversion<R, S, P> is true.
Complexity: Same as for the copy constructors of the underlying types. Constexpr, triviality and noexcept of underlying operations is propagated.
Guarantees: If an exception is thrown during the operation, the object is left in a partially completed state, as per the normal rules for the same operation on a
