Struct pallet_aura::pallet::Pallet

impl<T: Config> Pallet<T>

pub fn change_authorities(new: BoundedVec<T::AuthorityId, T::MaxAuthorities>)

Change authorities.

The storage will be applied immediately. And aura consensus log will be appended to block’s log.

This is a no-op if new is empty.

pub fn initialize_authorities(authorities: &[T::AuthorityId])

Initial authorities.

The storage will be applied immediately.

The authorities length must be equal or less than T::MaxAuthorities.

pub fn authorities_len() -> usize

Return current authorities length.

pub fn slot_duration() -> T::Moment

Determine the Aura slot-duration based on the Timestamp module configuration.

pub fn do_try_state() -> Result<(), TryRuntimeError>

Ensure the correctness of the state of this pallet.

This should be valid before or after each state transition of this pallet.

§Invariants

§`CurrentSlot`

If we don’t allow for multiple blocks per slot, then the current slot must be less than the maximal slot number. Otherwise, it can be arbitrary.

§`Authorities`

The authorities must be non-empty.
The current authority cannot be disabled.
The number of authorities must be less than or equal to T::MaxAuthorities. This however, is guarded by the type system.
