Structs
- Simple handler for an imbalance drop which decreases the total issuance of the system by the imbalance amount. Used for leftover credit.
- Special dust type which can be type-safely converted into a
Credit
. - An imbalance in the system, representing a divergence of recorded token supply from the sum of the balances of all accounts. This is
must_use
in order to ensure it gets handled (placing into an account, settling from an account or altering the supply). - Simple handler for an imbalance drop which increases the total issuance of the system by the imbalance amount. Used for leftover debt.
Traits
- A fungible token class where any creation and deletion of tokens is semi-explicit and where the total supply is maintained automatically.
- Trait for providing the ability to create new fungible assets.
- Trait for providing the ability to destroy existing fungible assets.
- Handler for when an imbalance gets dropped. This could handle either a credit (negative) or debt (positive) imbalance.
- Trait for providing balance-inspection access to a set of named fungible assets.
- Interface for enumerating assets in existence or owned by a given account.
- Trait for providing a basic fungible asset.
- A fungible token class where the balance can be set arbitrarily.
Type Definitions
- Imbalance implying that the total_issuance value is greater than the sum of all account balances.
- Imbalance implying that the total_issuance value is less than the sum of all account balances.
