Struct CoinManager

Source 
pub struct CoinManager {
    pub id: UID,
    pub treasury_cap: TreasuryCap,
    pub metadata: Option<CoinMetadata>,
    pub immutable_metadata: Option<ImmutableCoinMetadata>,
    pub maximum_supply: Option<u64>,
    pub supply_immutable: bool,
    pub metadata_immutable: bool,
}
Expand description

The purpose of a CoinManager is to allow access to all properties of a Coin on-chain from within a single shared object This includes access to the total supply and metadata In addition a optional maximum supply can be set and a custom additional Metadata field can be added. Holds all related objects to a Coin in a convenient shared function.

Fields§

§id: UID

The unique identifier of the object.

§treasury_cap: TreasuryCap

The original TreasuryCap object as returned by create_currency

§metadata: Option<CoinMetadata>

Metadata object, original one from the coin module, if available

§immutable_metadata: Option<ImmutableCoinMetadata>

Immutable Metadata object, only to be used as a last resort if the original metadata is frozen

§maximum_supply: Option<u64>

Optional maximum supply, if set you can’t mint more as this number - can only be set once

§supply_immutable: bool

Flag indicating if the supply is considered immutable (TreasuryCap is exchanged for this)

§metadata_immutable: bool

Flag indicating if the metadata is considered immutable (MetadataCap is exchanged for this)
