}

Trait for providing an interface for NFT-like assets which may be minted, burned and/or have attributes set on them.

Provided methods

fn mint_into(_instance: &Self::InstanceId, _who: &AccountId) -> DispatchResult

Mint some asset instance to be owned by who.

By default, this is not a supported operation.

fn burn_from(_instance: &Self::InstanceId) -> DispatchResult

Burn some asset instance.

By default, this is not a supported operation.

fn set_attribute(
    _instance: &Self::InstanceId,
    _key: &[u8],
    _value: &[u8]
) -> DispatchResult

Set attribute value of asset instance’s key.

By default, this is not a supported operation.

fn set_typed_attribute<K: Encode, V: Encode>(
    instance: &Self::InstanceId,
    key: &K,
    value: &V
) -> DispatchResult

Attempt to set the strongly-typed attribute value of instance’s key.

By default this just attempts to use set_attribute.
