Contracts

Main features

contract_assert replaces assert

• Unlike assert, contract_assert is a proper keyword

Four build options: the evaluation semantics

• ignore – do not check the assertion;
• enforce — check the assertion; if the check fails, print a message and terminate (the default behaviour);

Duration: 30–60 minutes (not more)

Agenda:

• Quick context (2 min) — “We’re here to decide X. Everyone’s read the RFC”.
• Address open questions (10–15 min) — Go through unresolved comments and open questions from the RFC
• Discussion (15–30 min) — Debate the options, raise new concerns
• Decision (5–10 min) — Make the call

Who should be there:

// The base class
template<class Crtp, class MsgT>
class Receiver { 
  void receive(MsgT) {
    static_cast<Crtp*>(this)->private_ += 1;
  }
};


// The derived class
