Struct pallet_bags_list::pallet::Pallet

pub struct Pallet<T, I = ()>(_);

The Pallet struct, the main type that implements traits and standalone functions within the pallet.

Implementations

impl<T: Config<I>, I: 'static> Pallet<T, I>

pub fn rebag( origin: OriginFor<T>, dislocated: <<T as Config>::Lookup as StaticLookup>::Source ) -> DispatchResult

Declare that some dislocated account has, through rewards or penalties, sufficiently changed its score that it should properly fall into a different bag than its current one.

Anyone can call this function about any potentially dislocated account.

Will always update the stored score of dislocated to the correct score, based on ScoreProvider.

If dislocated does not exists, it returns an error.

pub fn put_in_front_of( origin: OriginFor<T>, lighter: <<T as Config>::Lookup as StaticLookup>::Source ) -> DispatchResult

Move the caller’s Id directly in front of lighter.

The dispatch origin for this call must be Signed and can only be called by the Id of the account going in front of lighter. Fee is payed by the origin under all circumstances.

Only works if:

• both nodes are within the same bag,
• and origin has a greater Score than lighter.

pub fn put_in_front_of_other( origin: OriginFor<T>, heavier: <<T as Config>::Lookup as StaticLookup>::Source, lighter: <<T as Config>::Lookup as StaticLookup>::Source ) -> DispatchResult

Same as Pallet::put_in_front_of, but it can be called by anyone.

Fee is paid by the origin under all circumstances.

impl<T: Config<I>, I: 'static> Pallet<T, I>

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

impl<T: Config<I>, I: 'static> Pallet<T, I>

pub fn do_rebag( account: &T::AccountId, new_score: T::Score ) -> Result<Option<(T::Score, T::Score)>, ListError>

Move an account from one bag to another, depositing an event on success.

If the account changed bags, returns Ok(Some((from, to))).

pub fn list_bags_get(score: T::Score) -> Option<Bag<T, I>>

Equivalent to ListBags::get, but public. Useful for tests in outside of this crate.
