Module frame_support::traits::tokens::fungibles

The traits for sets of fungible tokens and any associated types.

Individual tokens in the fungibles set may be used when a fungible trait is expected using crate::traits::tokens::fungible::ItemOf.

Also see the frame_tokens reference docs for more information about the place of fungible traits in Substrate.

Structs

• DecreaseIssuance
  Simple handler for an imbalance drop which decreases the total issuance of the system by the imbalance amount. Used for leftover credit.
• Dust
  Special dust type which can be type-safely converted into a Credit.
• Imbalance
  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).
• IncreaseIssuance
  Simple handler for an imbalance drop which increases the total issuance of the system by the imbalance amount. Used for leftover debt.
• UnionOf
  Type to combine two fungibles::* implementations into one union fungibles::* implementation.

Traits

• Balanced
  A fungible token class where any creation and deletion of tokens is semi-explicit and where the total supply is maintained automatically.
• Create
  Trait for providing the ability to create new fungible assets.
• Destroy
  Trait for providing the ability to destroy existing fungible assets.
• HandleImbalanceDrop
  Handler for when an imbalance gets dropped. This could handle either a credit (negative) or debt (positive) imbalance.
• Inspect
  Trait for providing balance-inspection access to a set of named fungible assets.
• InspectEnumerable
  Interface for enumerating assets in existence or owned by a given account.
• Mutate
  Trait for providing a basic fungible asset.
• Refund
  Trait for refunding the existence deposit of a target asset account.
• Unbalanced
  A fungible token class where the balance can be set arbitrarily.

Type Aliases

• Credit
  Imbalance implying that the total_issuance value is greater than the sum of all account balances.
• Debt
  Imbalance implying that the total_issuance value is less than the sum of all account balances.
