Detailed Description

template<typename Tp>
struct tim::concepts::is_phase_id< Tp >

concept that specifies that a type is used for identifying a phase in some measurement. For example, tim::audit::incoming and tim::audit::outgoing can be added to overloads to distinguish whether the double type in double exp(double val) is val or whether it is the return value.

    void audit(audit::incoming, double val) { ... }
