Struct pallet_committee_management::manager::SessionAndEraManager

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

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.

Trait Implementations

impl<E, EM, T, C> SessionManager<<C as Config>::AccountId> for SessionAndEraManager<E, EM, T, C>

where E: EraInfoProvider, EM: EraManager, T: SessionManager<C::AccountId>, C: Config,

fn new_session(new_index: SessionIndex) -> Option<Vec<C::AccountId>>

Plan a new session, and optionally provide the new validator set.

fn end_session(end_index: SessionIndex)

End the session.

fn start_session(start_index: SessionIndex)

Start an already planned session.

fn new_session_genesis(new_index: u32) -> Option<Vec<ValidatorId>>

Same as new_session, but it this should only be called at genesis.
