pub struct SessionAndEraManager<E, EM, T, C>(PhantomData<(E, EM, T, C)>)
where
    E: EraInfoProvider,
    EM: EraManager,
    T: SessionManager<C::AccountId>,
    C: Config;
Expand description

SessionManager that also fires EraManager functions. It is responsible for rotation of the committee, bans and rewards logic.

The order of the calls is as follows: First call is always from the inner SessionManager then the call to EraManager fn if applicable.

  • New session is planned:
  1. Inner T::new_session invoked
  2. If session starts era EM::on_new_era invoked
  3. Logic related to new session from this pallet is invoked
  • Session ends:
  1. Inner T::end_session invoked
  2. Logic related to new session from this pallet is invoked
  • Session starts:
  1. Inner T::start_session invoked
  2. Logic related to the new session from this pallet is invoked
  3. If session starts era EM::new_era_start invoked
  4. If session starts era logic related to new era from this pallet is invoked

In the runtime we set EM to pallet_elections and T to combination of staking and historical_session.
