Struct pallet_bags_list::List

pub struct List<T: Config<I>, I: 'static = ()>(_);

The ONLY entry point of this module. All operations to the bags-list should happen through this interface. It is forbidden to access other module members directly.

Implementations

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

pub fn unsafe_regenerate(
    all: impl IntoIterator<Item = T::AccountId>,
    score_of: Box<dyn Fn(&T::AccountId) -> T::Score>
) -> u32

Regenerate all of the data from the given ids.

WARNING: this is expensive and should only ever be performed when the list needs to be generated from scratch. Care needs to be taken to ensure

This may or may not need to be called at genesis as well, based on the configuration of the pallet using this List.

Returns the number of ids migrated.

pub fn migrate(old_thresholds: &[T::Score]) -> u32

Migrate the list from one set of thresholds to another.

This should only be called as part of an intentional migration; it’s fairly expensive.

Returns the number of accounts affected.

Preconditions:

• old_thresholds is the previous list of thresholds.
• All bag_upper currently in storage are members of old_thresholds.
• T::BagThresholds has already been updated and is the new set of thresholds.

Postconditions:

• All bag_upper currently in storage are members of T::BagThresholds.
• No id is changed unless required to by the difference between the old threshold list and the new.
• ids whose bags change at all are implicitly rebagged into the appropriate bag in the new threshold set.

pub fn get_score(id: &T::AccountId) -> Result<T::Score, ListError>

Get the score of the given node,
