When implemented, pallet can work with TotalAggregates

Required methods

fn in_usergroup(account_id: &AccountId, user_group: &UserGroup) -> bool

Checks wether account_id is in a group user_group

fn set_usergroup(account_id: &AccountId, user_group: &UserGroup, is_in: &bool)

Adds account_id to a user_group or removes it from a group based on passed is_in bool

fn update_total(
    account_id: &AccountId,
    currency: &Currency,
    prev_balance: &SignedBalance<Balance>,
    delta_balance: &SignedBalance<Balance>
)

Updates TotalAggregates of a group when balance of account_id changes for delta_balance

fn iter_account(user_group: &UserGroup) -> Box<dyn Iterator<Item = AccountId>>

Used to iterate over all accounts of a user group

fn iter_total(
    user_group: &UserGroup
) -> Box<dyn Iterator<Item = (Currency, TotalAggregates<Balance>)>>

Used to iterate over currency total of a user group

fn get_total(
    user_group: &UserGroup,
    currency: &Currency
) -> TotalAggregates<Balance>

Deprecated, will be removed
