type AssetId = <T as Config>::CurrencyId

Means of identifying one asset class from another.

type Balance = <T as Config>::Balance

Scalar type for representing balance of an account.

fn total_issuance(asset: Self::AssetId) -> Self::Balance

The total amount of issuance in the system.

fn minimum_balance(asset: Self::AssetId) -> Self::Balance

The minimum balance any single account may have.

fn total_balance(asset: Self::AssetId, who: &T::AccountId) -> Self::Balance

Get the total amount of funds whose ultimate beneficial ownership can be determined as who.

fn balance(asset: Self::AssetId, who: &T::AccountId) -> Self::Balance

Get the balance of who which does not include funds which are exclusively allocated to subsystems of the chain (“on hold” or “reserved”).

fn reducible_balance( asset: Self::AssetId, who: &T::AccountId, preservation: Preservation, force: Fortitude ) -> Self::Balance

Get the maximum amount that who can withdraw/transfer successfully based on whether the account should be kept alive (preservation) or whether we are willing to force the transfer and potentially go below user-level restrictions on the minimum amount of the account.

fn can_deposit( asset: Self::AssetId, who: &T::AccountId, amount: Self::Balance, provenance: Provenance ) -> DepositConsequence

Returns true if the asset balance of who may be increased by amount.

fn can_withdraw( asset: Self::AssetId, who: &T::AccountId, amount: Self::Balance ) -> WithdrawConsequence<Self::Balance>

Returns Failed if the asset balance of who may not be decreased by amount, otherwise the consequence.

fn asset_exists(asset: Self::AssetId) -> bool

Returns true if an asset exists.

fn active_issuance(asset: Self::AssetId) -> Self::Balance

The total amount of issuance in the system excluding those which are controlled by the system.
