Concept definition

template<typename R>
concept Aleph::CA::Has_Master_Seed =  requires(R &r, std::uint64_t s) {
  { r.master_seed() } -> std::convertible_to<std::uint64_t>;
  r.set_master_seed(s);
}

Detailed Description

Concept: rule type that exposes a master RNG seed.

Stochastic rules built on Per_Thread_RNG follow this contract: the rule stores a master seed and offers master_seed() / set_master_seed(s) accessors. Checkpointing uses the concept to detect-and-restore the seed automatically.

Template Parameters

R	rule type.
