selfdestructing-cpp

===================

This is a small C++ "artwork" - classes that deliberately crash on object construction.

The goal is to create a policy DSL that is readable in English. The project is a work in progress, since there are lots of possibilites of use and configuration of such classes, considering the richness of the recent C++ standard.

Use?

----

A the primary use is (self-)education. Other uses may include debugging legacy code, class policy enforcement, and perhaps something else I cannot think of.

Test: see selfdestructing.cpp

````cpp

struct TestNumberCrash : public crashes::on<3>::copies {};

````

![on 3 copies](/doc/img/on_copies.png)

- crashes on 3 total copies of the originally created object

- doesn't crash on 3 total instances of the class

---

````cpp

struct TestCopyNrCrash : public crashes::after<3>::copies {};

````

![after 3 copies](/doc/img/after_copies.png)

- crashes on any 3rd copy of the original object

- doesn't crash on 3 total instances of the class 

---

````cpp

struct TestTotalNrCrash : public crashes::on_total<3,TestTotalNrCrash>::instances {};

````

![on total 3 instances](/doc/img/on_total_instances.png)

- crashes on instantiation of an object if 2 objects are alive

- doesn't crash on any creation if the total amount of instances is below 2

---

````cpp

struct TestAfterTotalNrCrash : public crashes::after_total<3,TestAfterTotalNrCrash>::instances {};

````

![after total 3 instances](/doc/img/after_total_instances.png)

- crashes after a third object instantiation of the class

---

Singular form aliases are also available, i.e. `crashes::on<1>::copy`.

There's no thread-safe policy yet.
