Detailed Description

Child actor runtime housekeeping information.

Member Function Documentation

spawn_demand_t rotor::detail::child_info_t::next_spawn ( bool abnormal_shutdown )

noexcept

checks whether new actor should be spawned

New actor can be spawned right now, a bit later, not spawned at all possibly with triggering supervisor shutdown.

void rotor::detail::child_info_t::spawn_attempt ( )

noexcept

recalculates the state upon spawn_attempt

The last last_instantiation is refreshed, and may be the child info becomes inactivated (due to restart_policy)
